Two soap bubbles of radii a and b coalesce to form a single bubble of radius c under isothermal conditions. If the external pressure is p_A , then the Surface Tension (T) of the soap solution is
Options
- AP_A 4 (c^3-a^3-b^3 ) (a^2+b^2-c^2 )
- BP_A 2 (a^3+b^3-c^3 ) (c^2-a^2-b^2 )
- CP_A 2 (a^2+b^2-c^2 ) (c^3-a^3-b^3 )
- DP_A 4 (c^2-a^2-b^2 ) (a+b-c)
Correct answer
A. P_A 4 (c^3-a^3-b^3 ) (a^2+b^2-c^2 )
