Working Of Soap

Work done in forming a soap bubble of radius R is W. Then workdone is forming a soap bubble of radius '2R' will be :

The surface tension soap solution is 3 xx 10^(-2) N/m then then the work done in forming a soap film of 20 cm xx 5 cm will be

If W is amount of work done in forming a soap bubble of volume V , then the amount of work done In forming a bubble of volume 2V from the same solution will be

The work done in forming a soap film of size 10 cm xx 10 cm will be , it if the surface tension of soap solution is 3xx 10^(-2) N/m

The amount of work done in forming a soap bubble of radius r = 1 cm (surface tension T = 3 xx 10^(-2) N//m ) is

The amount of work done in forming a soap film of size 10 cm x 10 cm is (Surface tension T=3xx10^(-2) N//m )

The work done is blowing a soap bubble of volume V is W the work done in blowing a soap bubble of volume of 2V is

The work done is blowing a soap bubble of volume V is W . The work done in blowing a soap bubble of volume 2V is

The ratio of the work done in blowing the soap bubbles of radii in the ratio 1 :2 is ,
