The liquid in the capillary tube will rise if the angle of contact is

A

If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.

B

If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

C

If Assertion is true but Reason is false.

D

If both Assertion and Reason are false.

Text Solution

Verified by Experts

The correct Answer is:
D
`k=(2T cos theta)/(r rho g) implies h prop cos theta`
and h=0 when `theta=90^(@)`
Also angle of contact can be `0^(@)` in any practical case.
So, both A and R are incorrect.
