Physics - Capacitor Question with Solution | TestHub

A parallel plate capacitor consisting of two circular plates of radius 10 cm is being charged by a constant current of 0.15 A . If the rate of change of potential difference between the plates is $7\times 10^8\mathrm{V}/\mathrm{s}$ then the integer value of the distance between the parallel plates is $($ Take, ${ϵ}_0=9\times 10^{-12}\frac{\mathrm{F}}{\mathrm{m}},\pi =\frac{22}{7})$ ________ $\mu \mathrm{m}$.
