Question

Figure shows two large metal plates P1 and P2, 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. [CBSE (F) 2009]

Answer

(i) Charges induced on outer surfaces of P₁ and P₂ are – Q and + Q respectively. When plates are released, they will tend to move away from one another; plate P1 will move towards + Q and P₂ towards – Q due to attraction.

(ii) The field pattern is shown in Fig.
