STANDARD Physics Electric Field MCQ Question
Type: MCQ-conceptual-Medium
Five equal charges each of value q are placed at the corners of a regular pentagon of side a. The electric field at the centre of the pentagon is
A
q / (4πε₀r²)
B
q² / (4πε₀r²)
C
2q / (4πε₀r²)
D
zero
Correct Answer
Option D
Detailed Explanation
The electric field at the centre of the pentagon would be zero due to symmetry, as the vector sum of the fields due to each charge cancels out.
