The figure shows some of the electric field lines corresponding to an electric field. The figure suggests:
1. EA > EB > EC
2. EA = EB = EC
3. EA = EC > EB
4. EA = EC < EB

Assertion (A): | Point charges \(q_{1}\) and \(q_{2}\) produce electric field of magnitude \(E_{1}\) and \(E_{2}\) at a point and potential \(V_{1}\) and \(V_{2}\) at the same point. The electric field due to both the charges at that point must be \(E_{1}+E_{2}.\) |
Reason (R): | The electric potential at that point due to both the charges must be \(V_{1}+V_{2}.\) |
