Question

electric field and electrostatic potential are represented by E and V then give the situation where E not equal to zero and V equal to zero ​

Answer 1

Answer:

we will arrange all charges on the vertices of a square such that similar charges must be on one side of the square

Then in that case electric field at center is non zero while electric potential is zero

Explanation:

Electric field is a vector quantity while electric potential is a scalar quantity

So due to superposition principle we need to add vector sum when electric field due to more than 2 charges is to be found

While in calculation of electric potential we do not require direction but we need to use the charge along with its sign

So here we know that

$E = \vec E_1 + \vec E_2 + \vec E_3......................................$

now we assume that we have four charges with same magnitude of charges but two charges are positive while other two are negative

Now we will arrange all charges on the vertices of a square such that similar charges must be on one side of the square

Then in that case electric field at center is non zero while electric potential is zero
