A square frame of each side ' \(\mathrm{L}\) ' is dipped in a soap solution and taken out. The force acting on the film formed is \((\mathrm{T}=\) surface tension of soap solution)
- A 2 TL
- B 8 TL
- C 12 TL
- D 16 TL
Answer & Solution
Correct Answer
(B) 8 TL
Step-by-step Solution
Detailed explanation
(B)
Length of four sides \(=4 \mathrm{~L}\)
\(\therefore\) Force due to surface tension \(=4 \mathrm{~L} \times 2 \mathrm{~T}=8 \mathrm{LT}\)
Length of four sides \(=4 \mathrm{~L}\)
\(\therefore\) Force due to surface tension \(=4 \mathrm{~L} \times 2 \mathrm{~T}=8 \mathrm{LT}\)
