A parallel plate capacitor with area $200 \mathrm {~cm} ^ { 2 }$ and separation between the plates 1.5 cm , is connected across a battery of emf V . If the force of attraction between the plates is $25 \times 10 ^ { - 6 } \mathrm {~N}$, the value of $V$ is approximately:
$$\left( \varepsilon _ { 0 } = 8.85 \times 10 ^ { - 12 } \frac { \mathrm { C } ^ { 2 } } { \mathrm {~N} . \mathrm { m } } \right) ^ { 2 } \right)$$
