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
