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_(1)r_(1)=h_(2)r_(2)`
` :. h_(2) =(h_(1)r_(1))/(r_(2)) =1.8 xx(r_(1))/(0.9r_(1)) = 2 cm `
