Water rises in a vertical capillary tube...

Water rises in a vertical capillary tube up to a length of 10 cm. If the tube is inclined at `45^@`, the length of water risen in the tube will be

A

10 cm

B

`10sqrt(2)cm`

C

`5sqrt(2) cm`

D

20 cm

Text Solution

Verified by Experts

The correct Answer is:
B
When capillary tube is tilled through an angle `theta`, then length of water risen in capallary.
`l=h/(cos theta)`
Here, `h=10 cm, theta=45^(@)`
`l=10/(cos 45^(@)) =10 sqrt(2)`
