Calculate for the rise of water in a capillary tube when kept veritcal in water whose radii is 1/4th of that capillry tube which when kept veritcal water rise in it upto a height of 3 mm

A

12 mm

B

10 mm

C

4 mm

D

3 mm

Text Solution

Verified by Experts

`h=(2Scostheta)/(rgp)`
`rArr " " hr=(2Scostheta)/(rhog)`
For the experiment `S,theta,rho,g` are same
`hr=(2Scostheta)/(rhog) ` =constant
`h_(1)r_(1)=h_(2)r_(2)`
`h_(2)=((r)/(r//4))3=13 mm`
