In the given figure a capacitor of plate area $A$ is charged up to charge $q$ . The mass of each plate is $m_{2}$ . The lower plate is rigidly fixed. Find the value of $m_{1}$ so that the system remains in equilibrium -

Options:

Answer:

Solution:

Now $T = m_{2} g + F_{e l e c} \dots (1)$

$T = m_{1} g . . . . . . . (2)$

$m_{1} g = m_{2} g + \frac{q^{2}}{2 A ε_{0}}$

$m_{1} = m_{2} + \frac{q^{2}}{2 A ε_{0} g}$
