Question

Assertion: When water in a bucket is whirled fast overhead, the water does not fall out at the top of the circular path. Reason: The centripetal force in this position on water is more than the weight of water.

TestHub · Accepted Answer

At the top, the weight (plus the normal reaction of the bucket) provides the necessary centripetal force.
Whirled fast, $\frac{m v ^{2}}{R} > m g$ , i.e. the required centripetal force exceeds the weight, so the weight alone cannot pull the water away from the circle and the water does not fall (Assertion true, Reason true and correctly explaining).
