A parallel-plate capacitor with circular plates of radius (R=0.10 mathrm{~m}) and separation distance (d=0.10 mathrm{~mm}) is charged

Question:

A parallel-plate capacitor with circular plates of radius \(R=0.10 \mathrm{~m}\) and separation distance \(d=0.10 \mathrm{~mm}\) is charged by a constant current of \(1.0 \mathrm{~A}\).

(a) What is the magnitude of the Poynting vector associated with the electric and magnetic fields at the edge of the space between the plates?

(b) What is the rate at which electromagnetic energy is delivered to the cylindrical space between the plates?
