Question

If the earth stops rotating, the apparent value of g on its surface will
(a) increase everywhere (b) decrease everywhere (c) remain the same everywhere (d) increase at some places and remain the same at some other places.

Answer 1

(d) increase at some places and remain the same at some other places.

Explanation:

If the earth stops rotating the apparent weight will increase at most of the places because the upward component of the centrifugal force due to rotation will disappear. But at poles it will not change because these places do not rotate in a circle on the earth's surface.
