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, if the earth suddenly shrinks. This is a golden opportunity for those candidates who want to get into the teaching profession in the state of Uttar Pradesh.

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?

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. Now hat will be height of a geostationary satellite above the surface of the earth? If the earth shrinks of half of its radius its mass remaining same the weight of the object on the earth will change to. Is moment of inertia of a body a constant quantity? About what axis would a uniform cube have its minimum moment of inerti A nollow sphere and a solid sphere having same mass and same radii are Two uniform circular discs having the same mass and the same thickness

For the upcoming cycle, a total of vacancies are expected.

.

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. Related: What happens in intergalactic space? Planets are formed by accretion, or when space dust collides and increasingly builds up into a larger mass. After Earth formed about 4. But once a planet forms, another process begins: atmospheric escape.

Two uniform circular discs having the same mass and the same thickness More Physics Questions Q1. As size of earth changes its moment of inertia changes. The time period of a simple pendulum inside a satellite orbiting the Earth will be. Find the moment of inertia of a uniform cylinder about an axis through If g1 is the gravitational acceleration of the earth at a height equal to half of the radius of the earth and g2 is the gravitational acceleration of the earth at a depth equal to half of the radius of the earth, then find the ratio of the g1 to g2. Slope of distance-time graph gives:. Radius of earth is 6. Given below are two statements: one is labeled as Assertion A and the other is labeled as Reason R. Gravitational law of attraction is given by:. 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.
