MHT CET 2025 Physics question
A regular hexagon of side 6 cm has a charge of 2C at each of its vertices, what is the potential at the centre of the hexagon?
Answer: (B)
Solution
In a regular hexagon the distance from the centre to every vertex equals the side, cm m. Potential is a scalar, so the contributions of the six equal charges simply add: \dfrac{1}{4πε_0}$ = 6× = 6× 3× =
