Question
The curves show the equipotential contours in the plane of three point charges, Q1, Q2, and Q3. The values of the potentials are in kV as indicated for the +5, 0, and -5 kV contours. The positions of the charges are indicated by the dots.
1. T/F Q1 is a negative charge.
2. T/F The potential energy of an electron at g is zero.
3. T/F The potential energy of an electron at j is positive.
4. T/F Charge Q1 is the largest negative charge.
5. T/F Charge Q2 has the largest magnitude of all.
6. T/F The electric potential at i is lower than at j.
The person who answers them all correctly and explains why gets the Best Answer!!!
Q2 Volts 5 rn cm1 5 The letters are on the equipotential contours.Explanation / Answer
1) Q1 is a negative charge because potential due to Q1 is negative
2) the potential energy at g will be zero because there is no potential
3) the potential energy at j is positive because potential is positive
4) teh charge Q1 is largest -ve charge because potential is equl to -5 at larger distance than Q2
5) charge q2 is not largest magnitud eof all because magnitude of Q1 is larger than Q2
6)electric potential at i will be greater than j because it is close to Q3
