Water rises to a height of 2 cm in a capillary tube . If its diameter is made `(2//3)^(rd)` , the water will now rise to a height of

A

6 cm

B

3 cm

C

2/3 cm

D

3/2 cm

Text Solution

Verified by Experts

The correct Answer is:
B
`(h_(2))/(h_(1)) = (d_(1))/(d_(2))`
`(d_(1))/(2/3d_(1))=3/2 `
` h _(2) = 3/2 xx 2 = 3 cm `
