Answer:
Surface Energy = 0.2 J
Explanation:
Given,
The surface tension of a liquid is 5 Newton per metre.
A thin film of the area 0.02 metre square is formed on a loop.
To find : Surface Energy
We know,
Surface energy = T * Area
here, as 2 films are formed because of ring.
therefore, Surface Energy = T × 2 × (A) = 5 × 2 × 0.02 = 0.2 J
