A soap bubble has radius \( R \), charge q, surface tension T. Find the excess pressure in it.
\( \mathrm{P} \)
(A) \( \frac{32 \pi^{2} R^{2} \varepsilon_{0} T-q^{2}}{32 \pi^{2} R^{4} \varepsilon_{0}} \)
(B) \( \frac{64 \pi^{2} R^{3} \varepsilon_{0} T-q^{2}}{32 \pi^{2} R^{4} \varepsilon_{0}} \)
(C) \( \frac{128 \pi^{2} R^{3} \varepsilon_{0} T-q^{2}}{32 \pi^{2} R^{4} \varepsilon_{0}} \)
(D) none of these
