Energy Stored & Force between Plates

In parallel plate capacitor, electric field between the plates is ' $E$ '. If the charge on the plates is ' $Q$ ' then the force on each plate is

Show answer and solution

Answer: (d)

Field due to one plate $= \frac{\sigma}{2\varepsilon_0} = \frac{E}{2}$ .
Force on the other plate: $F = Q \cdot \frac{E}{2}$
So the answer is (d) $\frac{QE}{2}$ .
