If earth were to rotate faster than its present speed, the weight of an object

A

Increase at the equator but remain unchanged at the poles

B

Decrease at the equator but remain unchanged at the poles

C

Remain unchanged at the equator but decrease at the poles

D

Remain unchanged at the equator but increase at the poles

Text Solution

Verified by Experts

The correct Answer is:
B
`g.=g-omega^2Rcos^2lamda=0`
For equator `(lamda=0)`
`g.=g-omega^2R`
For pole `(lamda=90^@)=g.=g`
