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/s then the integer value of the distance between the parallel plates is _____μₘ.
( Take, ε₀ = 9 × 10⁻¹² F/m, π = 22/7)
