Work per unit charge to move between points is: MCQ with Answer and Explanation

Work per unit charge to move between points is:
A. Capacitance
B. Electric field
C. Potential energy
D. Electric potential
Answer: Option D
Solution (By JKExamLibrary)
Potential difference V = W/q: work per unit charge. Electric field E = F/q: force per unit charge. Memory tip: 'Potential = work/charge (scalar); Field = force/charge (vector)'. Electrostatics definition frequently tested in competitive exams.
