A. increases
B. decreases
C. remains unchanged
D. may decrease or increase
✅ The correct answer is option B.
If speed of rotation of the earth increases, weight of the body decreases. This is because you see a moving body on the rotating earth’s surface itself is in the reference frame. So when the earth rotates, the centripetal force acts towards the centre of rotation.
