Two capillary tubes of diameters 1 mm and 2 mm are dipped in water . The rise in water level in 1 mm tube is 1.4 cm . The rise in another tube will be

A

1.4 cm

B

`0.7` cm

C

` 2.8 `cm

D

`0.28` cm

Text Solution

Verified by Experts

The correct Answer is:
B
`h_(1)d_(1) = h_(2)d_(2)`
` h_(2) = (h_(1)d_(1))/(d_(2))= (1.4xx1)/2= 0.7`
