Question: An electric capacitor consists of thin round parallel plates, each of radius R, separated by a distance l (l < < R) and uniformly charged

An electric capacitor consists of thin round parallel plates, each of radius R, separated by a distance l (l << R) and uniformly charged with surface densities σ and – σ. Find the potential of the electric field and the magnitude of its strength vector at the axes of the capacitor as functions of a distance x from the plates if x >> l. Investigate the obtained expressions at x >> R.
