    There was a Question bothering me.


    I tried solving it But couldn't So I finally went up to my teacher asked him for help . He told me that there was a formula for Electrostatic pressure $\rightarrow$

    $$\mbox{Pressure}= \frac{\sigma^2}{2\epsilon_0}$$

    And we had just to multiply it to the projected area = $\pi r^2$

    When i asked him about the pressure thing he never replied.

    So what is it actually.Can someone Derive it/Explain it please.
