A liquid rises to a height of 3.6 cm in capillary tube of radius r . If the radius of the capillary tube is made `0.75` r, then the height to which the liquid will rise in the capillary tube is

A

`3.6` cm

B

`2.4` cm

C

`4.8` cm

D

`1.8` cm

Text Solution

Verified by Experts

The correct Answer is:

C

`h_(2) =(h_(1)r_(1))/(r_(2)) = 3.6 xx 4/3 = 4.8 ` cm
