If the earth stops rotating about its axis, then the magnitude of gravity

A

increases everywhere on the surface of earth

B

will increases only at the poles

C

will not change at the poles

D

All of the above

Text Solution

Verified by Experts

The correct Answer is:
C
`g' = g - R omega^(2) cos^(2) phi`
At `phi = 90^(@)`, `g' = g`, independent of `omega`.

If earth stops rotating

If the earth stops rotating about its axis, then acceleration due to gravity remains unchanged at

Assertion : If the earth stops rotating about its axis, the value of the weight of the body at equator will decrease. Reason : The centripetal force does not act on the body at the equator.

Statement I: If the earth suddenly stops rotating about its axis, then the acceleration due to gravity will become the same at all the places. Statement II: The value of acceleration due to gravity is independent of rotation of the earth.

If the earth stops rotating about its axis , then what will be the change in the value of g at a place in the equitorial plane ? Radius of the earth = 6400 km.

On account of the earth rotating about its axis

By considering earth to be non spherical. STATEMENT -1 : As one moves from equator to the pole of earth, the value of acceleration due to gravity increases. and STATEMENT -2 : If earth stops rotating about its own axis, the value of acceleration due to gravity will be same at pole and at equator.

If the Earth stops rotating about its polar axis, what will be the effect on the value of acceleration due to gravity 'g' ? Will this effect be same at all places?

If earth suddenly stops rotating about its own axis, the increase in it’s temperature will be
