Question

Problem 3 : At what height from the centre
the Earth the acceleration due to gravity will h
1/4h of its value as at the Earth.​

Answer 1

Explanation:

So at the height of 6371 km the value of g is 1/4 th of its original value . How deep from the surface of the Earth is a point where the acceleration due to gravity is half the value on the Earth's surface? At a certain height, gravitational acceleration is 4% of its value at the surface of the earth.
