Under isothermal conditions two soap bubbles of radii a and b coalesce to form a single bubble of radius c. If external pressure is `P_e ` , the surface tension of soap solution is equal to :

A

`( P_O ( a^(3) + b^(3) -c^(3) ) )/( 4 ( a^(2) + b^(2) + c^(2) )`

B

`( 4 ( a^(3) + b^(3) - c^(3) ))/( ( a^(2) + b^(2) -c^(2) ) )`

C

`(P_0 ( c^(3) - a^(3) - b^(3) ) )/( 4 ( a^(2) + b^(2) - c^(2) ) )`

D

`( P( a^(3) + b^(3) - c^(3) ) )/( (a^(2) - b^(2) -c^(2) ) )`
