The excess of pressure inside a soap bubble than that of the outer pressure is
$(a) \frac{2T}{r} (c) \frac{T}{2r} (b) \frac{4T}{r} (d) \frac{T}{r}$
Text Solution
Verified by ExpertsThe correct answer is:
B
Excess pressure inside the soap $p = \frac{4T}{r}$ where r = radius of bubble $T =$ surface tension
