Consider a uniformly charged ring of radius R. Find the point on the axis where the electric field is maximum.

The maximum electric field at a point on the axis of a uniformly charged ring is E_(0) . At how many points on the axis will the magnitude of the electric field be E_(0)//2 .

The maximum electric field at a point on the axis of a uniformly charged ring is E_(0) . At how many points on the axis will the magnitude of the electric field be E_(0)//2 .

Calculate distance of the point from the centre of a uniformly charged ring on its axis, where it electric field intensity becomes maximum.

An unchanged conducting sphere of radius R is placed near a uniformly charge ring of radius R. Total charge on ring is Q. The centre of sphere lies on axis of ring and distance of centre of sphere from centre of ring is R

An unchanged conducting sphere of radius R is placed near a uniformly charge ring of radius R. Total charge on ring is Q. The centre of sphere lies on axis of ring and distance of centre of sphere from centre of ring is R

A uniformly charged disc of radius R with a total charge Q lies in the XY -plane. Find the electric field at a point at a point P, along the Z-a xis that passes through the centre of the discc perpendicular to its plane. Discuss the limit when R gt gt z . Strategy : By treating the disc as a set of concentric uniformly charged rings, the problem could be solved by using the result obtained in example for ring. Consider a ring of radius of radius r' and thickness as shown in figure.
