A soap bubble was slowly enlarged from a radius of 4cm to 6cm. The amount of work necessary for enlargement was 1.5 x 10^-4 joules. Calculate the surface tension of the soap bubble.​

Explanation:

From the question we are told that:

Radius :

Work

Generally the equation for Work done  is mathematically given by

Where

Therefore

it becomes positively charged by charging it
