Suppose that a parallel-plate capacitor has circular plates with radius R = 28 mm and a plate separation of 5.5 mm. Suppose also that a sinusoidal potential difference with a maximum value of 140 V and a frequency of 77 Hz is applied across the plates; that is,

V = (140 V) sin[2π(77 Hz)t].

Find B_max(R), the maximum value of the induced magnetic field that occurs at r = R.
