9. The net work J 10. The electric potential energy at point B could be determined by the following relation: 11. The electric potential energy at point A could be determined by the following relation: 12. The change in potential energy is determined by (relation) 13. Based on 9 and 12 we can determine the C 14. The change in V 15. electrons 16. At point A in the negative y-direction 17. At point B in the negative y-direction Consider the conguration of charges shown below. A small negatively charged object (3 uC) of mass 0.01 kg (ignore gravitational effects) is released with a velocity in the negative y direction of 16 m/s from location labeled A (y=0.5m). The particle, acting under no forces that are external to the system of 3 charged particles, ends up at location B (y=0.1m) with an instantaneous velocity of zero having moved in a straight line from A. You are to determine the charges on the two unknown Q's (located at x= -0.2 m and X: +0.2 m). Your answers should follow a logical progression. A / B\\ Q1 Q2 I C l I O I r 1. The particle is slowing down so it is experiencing (m/sz) in the positive y-direction. 2. Because of (1), there must be a in the positive ydirection 3. Because the moving charge has a the electric eld must 4. Therefore, Q1 and Q2 5. And Q1 and Q2 must also be 6. At point A the object has a J 7. At point B the object has a 0ft) J 8. The change in J
