A drop of water of mass `m` and density `rho` is placed between two weill cleaned glass plates, the distance between which is `d`. What is the force of attraction between the plates?
`(T=` surface tension)

A

`(Tm)/(2rhod^(2))`

B

`(4Tm)/(rhod^(2))`

C

`(2Tm)/(rhod^(2))`

D

`(Tm)/(rhod^(2))`

Text Solution

Verified by Experts

The correct Answer is:
C
`F=(2TA)/(d),m=rhoV=rhoV = rho Ad rArr A = (m)/(rhod)`
