The circuit in the figure consists of switch S, a 5.60 V ideal battery, a 25.0 MΩ resistor, and an airfilled capacitor. The capacitor has parallel circular plates of radius 4.80 cm, separated by 5.00 mm. At time t = 0, switch S is closed to begin charging the capacitor. The electric field between the plates is uniform. At t = 210 μs, what is the magnitude of the magnetic field within the capacitor, at radial distance 2.60 cm? Number Units
