A square frame of length L is immersed in soap solution and taken out. The force experienced by the square plate is

A

TL

B

2 TL

C

4 TL

D

8 TL

Text Solution

Verified by Experts

The correct Answer is:
D

F = 2 br
= 8TL
R = 2r
`dW = 4 pi R^(2)T (n^(1//3)-1)`
` = 4pi R^(2)T xx (2-1)`
` dW = 4 pi R^(2) T`
