Question

As a body moves to a place 1600 km above the surface of a planet then the value of acceleration due to gravity of that planet reduces to 9/16 of its value at the surface of that planet, Calculate the radius of planet.

Answer 1

Answer:6.272

picture given below explains you the full detailed answer...

Answer 2

Explanation:

Given : d=1600km

R=6400km

Acceleration due to gravity at a depth
