Question
Identify the potential energy across the charges shown.
- Low potential
- High potential
- Cannot be determined
- Incomplete information
Hint:
Low potential
The correct answer is: Low potential
- Potential energy depends upon the distance and the sign of charges.
- U= Kq1q2/r (where, K= 1/4πε. and r= distance)
- Therefore, it will be negative due to q1 and as the distance decreases, potential energy increases more in negative value.
- Therefore, if 2 unlike charges are bought closer, the potential energy decreases.
- So, the correct option is a.
