Question

what is the value of acceleration due to gravity at a height equal to half the radius of earth, from surface of earth?
(10 m/s' on earth's surface)
​

Answer 1

Howdy !!

40m/s2

Let the radius of earth from surface of earth is R and the height equal to half the radius of earth from surface of earth is h.

Thus, the value of acceleration at a height due to gravity is 40m/s2.
