The amount of energy required to form a soap bubble of radius 2 cm from a soap solution is nearly (surface tension of soap solution =0.03 N m^-1) [NEET 2023]

Question

Accepted Answer

Correct answer: B. (b) Given, surface tension, T=0.03 Nm^-1 Radius of soop bubble, r=2 cm=2 10^-2 m ∴ Amount of energy required, E=2 TA=2 0.03 4 (2 10^-2)^2=3.01 10^-4 J
