A regular hexagon of side 10 cm has a charge 1 C at each of its vertices. The potential at the centre of hexagon is [ 1 4 _0 = 9 10^9 SI unit ]

MHT CET 2024 Physics question

A regular hexagon of side 10 cm has a charge at each of its vertices. The potential at the centre of hexagon is

(A) volt
(B) volt
(C) voltCorrect
(D) volt

Answer: (C)

Solution

For a regular hexagon the distance from the centre to each vertex equals the side, cm m. Potential is a scalar, so the six contributions simply add: \dfrac{1}{4πε_0}$ = 6 × 9× ×
