Question

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

Options

  •  If E = 0, V must be zero. 

  •  If V = 0, E must be zero. 

  • If E ≠ 0, V cannot be zero. 

  • If V ≠0, E cannot be zero. 

  • None of the above.

Solution

None of the above.

Electric field, \[E = \frac{- dV}{dr}\] where V = electric potential
For E = 0,  V should be constant. 
So, when E = 0,  it is not necessary that V should be 0.
Hence, none of the above signifies the correct relation.
