Physics - Capacitor Question with Solution | TestHub

Two plates of mass m each are connected to mass M by two light inextensible strings. The pulleys are ideal. To hold system in equilibrium, we need to charge the plates by a battery of at least 8 volts. If distance between plates is $1\mu \mathrm{m}$ capacitance formed is $1\mu \mathrm{F}\left(\mathrm{g}=10\mathrm{m}/{\mathrm{s}}^2\right)$ What are possible values of M & m?
