The height at which weight of the body ...

The height at which weight of the body become `(1)/(16)` its weight on the surface of earth, is

A

5R

B

15 R

C

3 R

D

4 R

Text Solution

Verified by Experts

The correct Answer is:
C
`(g)/(g') =[(R + h)/( R)]^(-2)`
`(16)/(1) = [(R + h)/( R)]^(2)`
` (R + h)/( R) = 4`
h = 3R
