Question
Identify the potential energy across the charges shown.
- Low potential
- High potential
- Cannot be determined
- Incomplete information
Hint:
When unlike charges are far apart, PE increases.
The correct answer is: High potential
- Potential energy is inversely proportional to the distance between the charges and directly proportional to the product of the charges.
- For unlike charges it will be negative and decreases in negative (becomes more positive) when the distance increases.
- Therefore, when two unlike charges are far apart, their electrostatic potential energy increases.
- So, the correct option is b.
