The electric field is written as;
\(E = - \frac {dV}{dr}\)
CALCULATION:
As we know,
\(E = - \frac {dV}{dr}\)
When V is constant, E = 0
Therefore option 2) is correct
→The potential may also be present outside the charge region, therefore we have no charge inside the region and when the charge is placed outside then the electric field will change.
So options 3) and 4) are correct.
Hence options 2), 3) and 4) are the correct answer.
