Question

The electric potential is zero at a point in a an electric field .Will the electric field be necessarily zero at that point?


reason?

Answer please

Answer 1

Answer: No

Zero potential at a point does not necessarily mean that the electric field is zero at that point.

At a point midway between two equal and opposite charges and at a point of the equatorial line of a dipole , The potential is zero, but the electric field not.

terms related to the question :

Electric field:

The space surrounding an known electric charge q in which another charge (test charge) experiences an electrostatic force (may be of attraction or repulsion) is called electric field of the charge q (known charge).

 

Electric potential:

The work done in bringing the a unit positive charge from infinity  to a Point P in the electric field is called the Electric Potential at that point.

If 1 joule of work is done in carrying a test charge of 1 coulomb from infinity to a point in an electric field, then the potential at that point will be 1 Volt.

$V=\frac{W}{q0}$

1 V = $1JC^{-1}$

Answer 2

not necessarily the electric field is zero at a point where electric potential is zero, as for an electric dipole, the midpoint has potential zero but electric fields are still there.
