Q11. A proton (mass = 1.67 x 10 kg, charge = 1.60 x 10-19 C) moves from point A to point B under the influence of an electrostatic force only. At point A the proton moves with a speed of 30 km/s. At point B the speed of the proton is 80 km/s. Determine the potential difference V8 -VA? A.-25 V B.-15 V C.-20 V D.-8 V E. -29 V Q12. If a = 30 cm, b = 20 cm, q= +3 nC, in the figure, what is the potential difference VA-VB? B A. 25 V D. 15 V B. 30 V E. 20 V C. 10 V Q13. Points A (at (2, 3) m) and B [at (5, 7) m) are in a region where the electric field is uniform and given by E = - 41 - 61 N/C. What is the potential difference Vp-VA? A. 36 V B. 28 V C. 20 V D. 40 V E. 32 V
