Q. 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 life moving down with an acceleration
C) At the poles
D) In a lift moving up with an acceleration
Explanation
(b) When life is accelerated downwards, the observed weight of body in a lift decreases. Hence, to counter balance the upward pull due to surface tension on the liquid meniscus, the height through which the liquid rises must increase
