If radius of the earth contracts 2% and ...

If radius of the earth contracts `2%` and its mass remains the same, then weight of the body at the earth surface

A

will decrease

B

will increase

C

will remain the same

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
b
`g=(GM)/(R^(2))" "therefore (Deltaw)/(w)=(Deltag)/(g)=-2(DeltaR)/(R)`
As, R decreases, the weight increases.
