    Let Q represent the charge on a parallel plate capacitor and E the electric field between the  plates, then each plate of the capacitor experiences a force of magnitude

    A)  zero            

    B)  \[QE\]

    C)  \[\frac{1}{2}QE\]          

    D)  \[2QE\]

    Correct Answer: C

    Solution :

    : Intensity of field\[E=\frac{q}{{{\varepsilon }_{0}}A}=\frac{Q}{{{\varepsilon }_{0}}A}\] Force between plates \[=\frac{{{q}^{2}}}{2{{\varepsilon }_{0}}A}=\frac{{{Q}^{2}}}{2{{\varepsilon }_{0}}A}\] \[=\frac{q}{2}\times \frac{q}{{{\varepsilon }_{0}}A}=\frac{qE}{2}=\frac{QE}{2}\]
