Show that the electric field at any point is equal to negative potential gradient at the point.

The Electric field at a point is

The Electric field at a point is

In an electric dipole, at which point is the electric potential zero?

Can an induced electric field exist at a point in space, when no magentic field is paresent at that point.

An alpha particle is placed in an electric field at a point having electric potential 5V. Find its potential energy ?

Each of the batteries shown in figure has an emf equal to 5 V. Show that the magnetic field B at the point P is zero for any set of values of the resistances .

Electric potential at any point in equatorial plane of a dipole is ………. .

The electric field and the electric potential at a point are E and V respectively.

In the following question a statement of assertion (A) is followed by a statement of reason (R ) A: the potential difference between two concentric sphereical shells depends only on the charge of inner shell R : the electric field in the region in between two shells depedns on the charge of inner shell and electric field is the negative of potential gradient.

When a 2 mu C charge is carried from point A to point B, the amount of work done by the electric field is 50 mu J . What is the potential difference and which point is at a higher potential ?
