Question

Charge of 5 μC is at each of the vertices of a regular hexagon of side 10 cm. Determine the electric potential at the centre of the regular hexagon.

Answer 1

For Hexagonal shape
OA = OB - OC = OD = OE = OF = 10cm = 0.1 m
Potential at O

VO = VA + VB + VC + VD + VE + VF = 6VA

Due to equal of charge and distance
