alleryElectric potential at infinity in the standard syllabus convention is taken as
Athe work done against gravity
B+∞
Czero
Dnegative of the source potential
Answer & Solution
Correct answer: C. zero
1. Potential is defined up to an additive constant; choosing V(∞) = 0 fixes the constant.
2. With this choice, V due to a +Q point charge is positive everywhere finite.
3. The other options have no physical basis.
