A capillary tube of area of cross-section A is dipped in water veritcally. Calculate the amount of heat evolved as the water rises in the capillary tunbe upto height h. The density of water is `rho`

A

`(Arhogh^(2))/(2)`

B

`Agh^(2)rho`

C

`2Agh^(2)rho`

D

None of these

Text Solution

Verified by Experts

(a) Heat evolved =Potential energy of water
`=(mgh)/(2)=(rhoAhgh)/(2)=(rhoAh^(2)g)/(2)`
