NEET 2017 Physics Variation of g MCQ Question

Type: MCQ-numerical-Medium-Class 11

The acceleration due to gravity at a height 1 km above the earth is the same as at a depth d below the surface of earth. Then:

A

d = 1/2 km

B

d = 1 km

C

d = 3/2 km

D

d = 2 km

Correct Answer

Option D

Detailed Explanation

The acceleration due to gravity decreases with height and depth. Using the formula for variation of g with height and depth, we find that d = 1/2 km.
