A) \[\frac{{{Q}^{2}}}{{{\varepsilon }_{0}}{{A}^{2}}}\]
B) \[\frac{{{Q}^{2}}}{2{{\varepsilon }_{0}}{{A}^{2}}}\]
C) \[\frac{{{Q}^{2}}}{{{\varepsilon }_{0}}A}\]
D) \[\frac{{{Q}^{2}}}{2{{\varepsilon }_{0}}A}\]
Correct Answer: D
Solution :
Force between the plates of a parallel plate capacitor\[\left| F \right|=\frac{{{V}^{2}}A}{2\,{{\varepsilon }_{0}}}=\frac{{{Q}^{2}}}{2\,{{\varepsilon }_{0}}A}=\frac{C{{V}^{2}}}{2\,d}\]You need to login to perform this action.
