Fig. shows two large metal plates, \[{{P}_{1}}\]and \[{{\mathbf{P}}_{\mathbf{2}}}\] tightly held against each other and placed between two equal and unlike point charges perpendicular to the line joining them.    (i) What will happen to the plates when they are released? (ii) Draw the pattern of the electric field lines for the system.                                  

Answer:

                (i) When released, the two plates tend to move apart slightly due to the charges induced in them. (ii) The pattern of the electric field lines for the system is shown in Fig.
