If the earth suddenly shrinks

Acceleration due to gravity of the earth having mass M and radius R on earth surface is given by:. Last updated on Mar 31, In this year's recruitment cycle, a total of vacancies were released. This is a golden opportunity for those candidates who want to get into the teaching profession in the state of Uttar Pradesh.

If the radius of the earth contracts to half of its present value without change in its mass, what will be the new duration of the day? If earth shrinks then the duration of day. The sun rotates about its axis once in 27 days. If it suddenly shrinks to one-eighth of its original volume, mass remaining same, then what will be its new period of rotation? The height of geostationary orbit above the surface of the earth is h. Radius of the earth is R. The earth shrinks to half its present radius mass remaining unchanged.

If the earth suddenly shrinks

If the earth suddenly shrinks without changing mass to half of its present radius, the acceleration due to gravity will be. If the earth suddenly shrinks without changing and half of its present radius , the acceleration due to gravity be. If the earth shrinks without change in mass, what will be the effect on the value of acceleration due to gravity g? Statement I: If the earth suddenly stops rotating about its axis, then the acceleration due to gravity will become the same at all the places. Statement II: The value of acceleration due to gravity is independent of rotation of the earth. Suppose the earth shrinks such that its radius decreases to half the present value. What will be the acceleration due to gravity on the surface of the earth? A satellite is revolving around earth in its equatorial plane with a period T. If the radius of earth suddenly shrinks to half without change in the mass. Then, the new period of revolution will be. Statement-1 : If earth shrink without change in mass to half of its present size, length of the day would become 6 hours. Statement-2 : When the size of the earth will change, its moment of inertia will also change. If earth shrink without change in mass to half it's present size. Length of the day would become 6 hours.

One electron volt is equal to :. A satellite is revolving around earth in its equatorial plane with a period T. Acceleration due to gravity of the earth having mass M and radius R on earth surface is given by:.

.

If the Earth suddenly shrinks without changing its mass to half its current radius,then the new gravitational acceleration at earths surface will be. If the Earth were to suddenly shrink to half its current radius while keeping its mass constant, the gravitational acceleration g at the Earth's surface would be four times its current value. If the Earth's radius becomes half its current value, the new radius R' will be:. Therefore, the gravitational acceleration at the Earth's surface will become four times its current value if the Earth suddenly shrinks to half its current radius while maintaining a constant mass. JEE Main session 2 exam city intimation slip expected by March last week. Dont't have an account?

If the earth suddenly shrinks

Like any good gift giver, Earth is constantly giving and receiving materials with the surrounding solar system. For instance, dust speeding through space regularly bombards our planet in the form of shooting stars, and gases from Earth's atmosphere regularly seep out into space. So, if Earth is continuously giving away matter, as well as acquiring new material, is it expanding or shrinking? Because of Earth's gaseous gifts to space, our planet — or, to be specific, the atmosphere — is shrinking, according to Guillaume Gronoff, a senior research scientist who studies atmospheric escape at NASA's Langley Research Center in Virginia. However, we're not shrinking by much, he said. Related: What happens in intergalactic space? Planets are formed by accretion, or when space dust collides and increasingly builds up into a larger mass.

Suppose the earth shrinks such that its radius decreases to half the present value. Concept : Acceleration due to gravity : The acceleration achieved by any object due to the gravitational force of attraction by the earth is called acceleration due to gravity by the earth. The acceleration due to gravity g and mean density of earth rho are re The earth shrinks to half its present radius mass remaining unchanged. The center of gravity is the point where:. What will be the acceleration due to gravity on the surface of the earth? Is moment of inertia of a body a constant quantity? If the earth suddenly shrinks without changing and half of its present radius , the acceleration due to gravity be. As size of earth changes its moment of inertia changes. If the change in the value of g at a height h above the surface of ear Get Started. Which physical quantities are represented by the product of moment of A nollow sphere and a solid sphere having same mass and same radii are View Solution.

What would happen if our Sun—as it actually exists, in the present—suddenly decreased in mass, plummeting from 1 solar to mass to a mere.

According to Kepler's first law, the planets move around the Sun:. The acceleration due to gravity at the centre of earth is. Now hat will be height of a geostationary satellite above the surface of the earth? Write SI unit of angular momentum:. A satellite is revolving around earth in its equatorial plane with a period T. When a body is taken from the equator to the poles, its weight. Is moment of inertia of a body a constant quantity? Weight of a body is maximum at This question was previously asked in. State the expression for the moment of inertia of a solid cylinder of Length of the day would become 6 hours. The weight of a body at the centre of the earth is. Reason R : The force of gravity of earth keeps the satellite in circular orbit around it. Testbook Edu Solutions Pvt. If the Earth suddenly shrinks so as reduce its volume, mass remaining unchanged, what will be the effect on the duration of the day?
