Electrostatics: JEE Main 2025 Physics question

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 $7 \times 10^8$ V/s then the integer value of the distance between the parallel plates is (Take, $\epsilon_0 = 9 \times 10^{-12}$ F/m, $\pi = \frac{22}{7}$) ______ $\mu$m.
