JEE MainPhysicsCapacitorNumerical+4 / −1
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 7×108 V/s7 \times 10^8 \mathrm{~V} / \mathrm{s}7×108 V/s then the integer value of the distance between the parallel plates is (\left(\right.( Take, ϵ0=9×10−12 F m,π=227)\left.\epsilon_0=9 \times 10^{-12} \frac{\mathrm{~F}}{\mathrm{~m}}, \pi=\frac{22}{7}\right)ϵ0​=9×10−12 m F​,π=722​)‾\underline{\hspace{2cm}}​μm\mu \mathrm{m}μm.
