Multiplechoice questions may continue on the next column or page find all choices before answering. 001 (part 1 of 2) 10.0 points A proton is accelerated through a potential difference of 3 . 5 10 6 V. a) How much kinetic energy has the proton acquired? Answer in units of J. 002 (part 2 of 2) 10.0 points b) If the proton started at rest, how fast is it moving? Answer in units of m / s. 003 10.0 points Points A (1 m, 4 m) and B (3 m, 7 m) are in a region where the electric field is uniform and given by vector E = E x + E y , where E x = 4 N / C and E y = 3 N / C. What is the potential difference V A V B ? Answer in units of V. 004 10.0 points Consider a circular arc of constant linear charge density as shown below. x y 3 7 + + + + + + + + + + + O r What is the potential V O at the origin O due to this arc?...
