STANDARD Physics Electric Potential MCQ Question
Type: MCQ-numerical-Medium
A hexagon of side 8 cm has a charge 4 μC at each of its vertices. The potential at the centre of the hexagon is
A
2.7 × 10⁶ V
B
7.2 × 10¹¹ V
C
2.5 × 10¹² V
D
3.4 × 10⁴ V
Correct Answer
Option A
Detailed Explanation
As shown in the figure, O is the centre of hexagon ABCDEF of each side 8 cm. As it is a regular hexagon, OAB, OBC, etc. are equilateral triangles. The potential at O is calculated using the formula V = 6 × (q / (4πε₀r)) = 2.7 × 10⁶ V.
