Water rises in a capillary tube to a height `h`. It will rise to a height more than `h`

A

on the surface of sun

B

in a lift moving down with an acceleration

C

at the poles

D

in a lift moving up with an acceleration

Text Solution

Verified by Experts

The correct Answer is:
B
When lift is accelerated downwards, the observed weight of body in a lift decreases. Hence, to counter balance the upwards pull due to surface tension on the liquid meniscus, the height through which the liquid rises must increases.
