Question

What is Electric Field due to charged Circular Ring?

Answer

Electric Field due to charged Circular Ring - Electric field due to a charged circular ring of radius R and charge Q at a distance x from the centre of the ring on its axis is given by At centre, x = 0, so E_centre = 0. At a point on the axis such that x >> R, E = kQ/x² If x = ±R/√2, then [E_max = 2kQ/3√3R²]
