A non-conducting semi circular disc (as shown in figure) has a uniform surface charge density sigma . The ratio of electric field to electric potential at the centre of the disc will be

Finding Electric Field From Electric Potential

In the above problem, find the electric field and electric potential at the centre of the sphere due to induced charges on the sphere?

A charge Q is distribution over a metal sphere of radius R. What is the electric field and electric potential at the centre ?

Establish the relation between electric field and electric potential at a point. Draw the equipotential surface for an electric field pointing in +Z direction with its magnitude increasing at constant rate along -Z direction

Assertion : Due to two point charges electric field and electric potential can't be zero at some point simultaneously. Reason : Field is a vactor quantity and potential a scalar quantity.

Two point charges of +3muC are placed 2xx10^(-3) m apart from each other. Calculate (i) electric field and electric potential at a distance of 0.6m from the dipole in broad-side-on position (ii) electric field and electric potential at the same point after rotating the dipole through 90^(@) .
