Question
How does the superposition principle apply to the absolute potential at a point due to a number of point charges?
Correct Answer
Option C is the correct answer.
Detailed Explanation
The text states: 'Because of the superposition principle and the scalar nature of potential difference, the absolute potential at a point due to a number of point charges is V = k₀ Σ qᵢ/rᵢ' (Page 11, Equation 25.3). This implies an algebraic sum.
Hint
Remember that potential difference is a scalar quantity, unlike electric field which is a vector.
