Toppr Admin · Accepted Answer

The correct option is B continuous collection of concentric rings
A thin uniformly charged disc can be assumed to be made of continuous collection of concentric rings. Electric field at a point is then calculated due to any one such ring and then it is integrated over all the rings to find the electric field due to whole charged disc.
