A

B

C

D

## each goes decreasing

Solution
Verified by Toppr
Correct option is D)

## The acceleration due to gravity goes on decreasing for both the scientists A and B.Since,  So, as the distance from the center of earth increases, the value of g decreases.Let scientist A be at a depth . Then only attraction is due to the sphere , where   is the radius of earth. As the attraction due to rest of the earth cancels out, so the value of decreases.
