A liquid rises to a height of 1.8 cm in a glass capillary A another glass capillary B having diameter 90% of capillary A is immersed in the same liquid the rise of liquid in capillary B is

A

1.4 cm

B

1.8 cm

C

2.0 cm

D

2.2 cm

Text Solution

Verified by Experts

The correct Answer is:
C
`h prop implies h_1/h_2 =r_2/r_1 =(0.9r)/r`
`implies h_2 = (1.8)/(0.9) = 2cm`
