NEET Physics Electric Potential MCQ Question
In the diagram shown above, if a charge q₀ is brought to the center E of the square, what is the electrostatic potential at point E due to all four charges at the corners?
Zero
Positive
Negative
Cannot be determined
Correct Answer
Detailed Explanation
The electrostatic potential at point E due to multiple point charges is the algebraic sum of the potentials due to individual charges. Since the charges at the corners are arranged symmetrically with opposing signs, their potentials cancel each other out at the center, resulting in a net potential of zero.
