Detailed Solution

The surface of the conductor is an equipotential surface .

Charge density at a point is inversely proportional to the radius of curvature of the surface at that point .

Electric field is ditectly proportional to the charge density . For surface of irregular shape , radius of curvature is different at different points , so intensity of electric field at different points will be different .
