Question

A parallel plate capacitor with circular plates of radius 1m
has a capacitance of 1nF At time t=0, it is connected for charging
in series with a resistor R = 1 M ohm across a 2V baterry Calculate
the magnetic field at a point P, halfway between the centre and the
periphery of the plates, after t=10 raised to the power -3
seconds

Dear Student , Here in this case , Here , C=10-19 Fx=0·5 mr=1 mR=106 ΩV =2 voltA=π m2Now distance between the two plates be ,d=ε0AC=2·8×108 mthus the plates are far away and the electric field near the first plate will be ,E=q2ε0ABy RC circuit analysis , considering the Gaussian surface shown by the cylinder of height 0·5 m,
