NEET Physics (general) MCQ Question
Type: MCQ-fact-Medium-Class 12
What is the formula for calculating the work needed to bring a charge to a point D in the presence of other charges at points A, B, and C?
A
Work = -q(q1/d1 + q2/d2 + q3/d3) / (4πε0)
B
Work = q(q1 + q2 + q3) / (4πε0)
C
Work = -q^2 / (4πε0d)
D
Work = q^2 / (4πε0d^2)
Correct Answer
Option A
Detailed Explanation
The correct formula given in the context is Work = -q(q1/d1 + q2/d2 + q3/d3) / (4πε0), which reflects the potential at point D due to multiple charges and the work done to bring charge -q to that point.
