Derive an expression for the strength of electric field intensity at a point on the axis of a uniformly charged circular coil of radius R carrying charge Q.

The line charge density of a semicircular ring of radius R is lambda . Find electric field intensity at the centre of the ring. What is the total charge of an electric dipole?

The electric field strength due to a circular loop of charge of radius R are uniform linear density of charge lambda , at its centre is proportonal to

Assertion: Three equal charges are situated on a circle of radius r such that they form on equilateral triangle, then the electric field intensity at the centre is zero. Reason: The force on unit positive charge at the centre, due to the three equal charges are represented by three sides of a triangle taken in the same order. Therefore, electric field intensity at centre is zero.
