The squares $S_1$ and $S_2$ are shown below with the charges arranged at their corners.
What is the relation between electric potentials $V_1$ and $V_2$ at the centres of the squares $S_1$ and $S_2$?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → $V_1=V_2=0$
∴ Due to superposition principle, all the charges at vertices on squares cancels out each other potential.
