Force due to Surface Tension

A square frame of each side L is dipped in a soap and taken out, the force acting on the film formed is ( T = surface tension of soap solution)

Show answer and solution

Answer: (b)

A film has two surfaces, so $F = 2T \times \text{perimeter}$ .
Perimeter $= 4L$ , so $F = 2T(4L) = 8TL$ .
So the answer is (b) $8TL$ .
