Assertion : A stone and a feather dropped from the same height do not reach the ground at the same time. Reason : Acceleration due to gravity is dependent on the mass of the object.

Say True or False. At the poles, the acceleration due to gravity is 9.77m//s^(2)

At what height from the center of the Earth the acceleration due to gravity will be 1/4th of its value as at the earth.

The masses of two planets are in the ratio 1:2 their radii are in the ratio 1:2. Find the ratio of the acceleration due to gravity on the planets .

The value of acceleration due to gravity at poles is ________________ m//s^(2)
