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) |
50.1 × 10−4 J 30.16 × 10−4 J 5.06 × 10−4 J 3.01 × 10−4 J |
3.01 × 10−4 J |
$\text{The amount of energy required to form a soap bubble of radius 2 cm from a soap solution is } U = 2TA = 2 T \times 4\pi R^2 = 2\times 0.03 \times 4\pi \times 0.02^2 = 3.01\times 10^{-4} J$ |
