Home » Mechanics » Gravitation » Question

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

1. d = 1 km
2. d = 3 km
  2
3. d = 2 km
4. d = 1 km
  2

Correct Option: C

According to question, g_h = g_d

g			1 -	2h		= g		1 -	d
				R_e					R_e

Clearly , d = 2h = 2 km
