The correct expression for the potential at a point distance r from a charge q in an electric field is?
- _q24ΟΞ΅or2
- _q24ΟΞ΅or
- _q4ΟΞ΅or2
-
\(\frac{q}{4ΟΞ΅_or}\)
The correct answer is: D
Explanation
Electric potential is work done in taking a unit mass or charge from infinity to that point
| V = | w | = | Fr | = | Q1Q2 | x | r |
| Q | Q | 4ΟΞ΅or2 | Q1 |
| = | _q |
| 4ΟΞ΅or |
