Suppose that angular velocity of rotation of earth is increased. Then, as a consequence :

A

Weight of the object everywhere on the earth will increase

B

Weight of the object everywhere on the earth will decrease

C

There will be no change in weight anywhere on the earth

D

Except at poles, weight of the object on the earth will decrease

Text Solution

Verified by Experts

The correct Answer is:
D
Apparent weight =`w-momega^2r`
r is max. At equator equal to R
r is zero at the pole.
Hence if `omega` is increased apparent weight decreases .
