Question

The electrostatic pressure on a charged surface having a surface charge density $\sigma\ C / \mathrm{m}^{2}$\

Professor PC Thomas Classes · Answer

Electrostatic pressure\ $=$ Force on unit area\ $=$ Charge on unit area $	imes$ field\ $=\sigma 	imes \frac{\sigma}{2 \varepsilon_{0}}=\frac{\sigma^{2}}{2 \varepsilon_{0}}$\
