The height of water in a capillary tube ...

The height of water in a capillary tube os radius 2 cm is 4 cm . What should be the radius of capillary , if the water rises to 8cm in tube ?

A

1 cm

B

0.1 cm

C

2 cm

D

4 cm

Text Solution

Verified by Experts

The correct Answer is:
A
` r_(2) = (h_(1)r_(1))/(h_(2))`
` = (4 xx 2)/8 = 1 ` cm
