In a capillary tube, water rises by `1.2mm`. The height of water that will rise in another capillary tube having half the radius of the first, is

A

`1.2mm`

B

`2.4mm`

C

`0.6mm`

D

`0.4mm`

Text Solution

Verified by Experts

The correct Answer is:
B
`hprop(1)/(r )` `because` `r_1h_1=r_2h_2impliesh_2=(r_1h_1)/(r_2)=2.4mm`
