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,

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.

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.

If the Earth suddenly shrinks so as reduce its volume, mass remaining unchanged, what will be the effect on the duration of the day? Radius of earth is 6.

.

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.

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.

Now hat will be height of a geostationary satellite above the surface of the earth? Gravitational law of attraction is given by:. When a body is taken from the equator to the poles, its weight Testbook Edu Solutions Pvt. 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. Which physical quantities are represented by the product of moment of The weight of a body at the centre of the earth is

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. In order to understand what impact this would have on our solar system and on Earth, especially , you need to have a basic understanding of how mass is related to gravity. Essentially, an increase in mass means an increase in gravity, while a decrease in mass means a decrease in gravity.

If a planet consists of a satellite whose mass and radius were both ha 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. Suppose the earth shrinks such that its radius decreases to half the present value. View Text Solution. A body weighs N on the surface of the earth. The weight of an object in the coal mine, sea level and at the top of the mountain, are respectively W1, W2, and W3, then. 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 the earth shrinks without change in mass, what will be the effect on the value of acceleration due to gravity g? Weight of a body is maximum at Geostationary satellite rotates.
