    A parallel plate capacitor has an electric field of \[{{10}^{5}}\,V/m\] between the plates. If the charge on the capacitor plate is \[1\mu \,C\], the force on each capacitor plate is [Orissa JEE 2002]

    A)            \[0.5\,N\]                              

    B)            \[0.05\,N\]

    C)            \[0.005\,N\]                         

    D)            None of these

    Correct Answer: B

    Solution :

               \[F=\frac{C{{V}^{2}}}{2d}=\frac{Q\times E}{2}=\frac{{{10}^{-6}}\times {{10}^{5}}}{2}=0.05N\]
