The electric potential $V$ at a distance $r$ from a point charge $q$ is given by:
- A.$kq/r^2$
- B.$kq/r$
- C.$kqr$
- D.$kq^2/r$
Show correct answer & step-by-step solution
Correct answer: B — $kq/r$
Solution
The electric potential due to a point charge at a distance is defined as the work done per unit charge to bring a test charge from infinity to that point. The standard formula is .
