A square wire frame of L is dipped in a liquid, on taking out a membrane is formed. If the surface tension of liquid is T, force acting on the frame will be

A

2 TL

B

4 TL

C

8 TL

D

10 TL

Text Solution

Verified by Experts

The correct Answer is:
C
Force on each side = 2TL (due to two surfaces)
Force on the frame = 4(2TL) = 8TL
