Water in a bucket is whirled in a vertical circle with a string attached to it. The water does not fall down even when the bucket is inverted at the top of its path. We conclude that in this position
(a) mg =mv2/r
(b) mg is greater than mv2/r
(c) mg is not greater than mv2/r
(d) mg is not less than mv2/r

(c) mg is not greater than mv2/r
Explanation :
At the top position the weight of the water mg acts downward to bring it down while due to inertia water tries to escape upward with a force mv²/r on the bucket. Therefore if the water is not falling at the top position it means mg< mv²/r.
