If the earth stops rotating, the value of ‘ g ’ at the equator will

Options

A. increases
B. decreases
C. no effect
D. None of these

Answer

A

Explanation

Then earth possesses rotational motion about an axis through its poles. The value of acceleration due to gravity at a place (at given latitude) is affected due to its rotational motion. If earth ceases to rotate, the weight of a body at equator will increase. But no effect on the weight at poles. The effect of rotation of the earth on acceleration due to gravity is to decrease its value. Therefore if the earth stops rotating, the value of g will increase.
