A parallel plate capacitor with circular plates of radius 1 m has a capacitance of 1 nF. At t = 0, it is connected for charging in series with a resistor R = 1 MΩ across a 2 V battery. Then the electric field at a point P, halfway between the centre and the periphery of the plates, after t = 10^-3 s is.
