Answer in units of In. 002 (part 2 of4) _ Now nd the change in electric potential along this path. Answer in units of V. 003 (part 3 of 4) Find the change in potential energy when a proton (1013, : 1.7 x 1027 kg and 1gp : 1.6 X 1019 C) moves from B to A. Answer in units of J. 004 (part 4 of 4) Find the change in potential energy when an electron (rm,- 2 9.1 X 1031 kg and qt: = 1.6 X 1019 C) moves from B to A. Answer in units of .l. 005 It takes 110 J of work to move 1.1 C of charge from the negative plate to the positive plate of a parallel plate capacitor. W'hat voltage difference exists between the plates? Answer in units of V. 006 Two parallel conducting plates are connected to a constant voltage source. The magni- tude of the electric eld between the plates is 1526 N / C. If the voltage is doubled and the distance 1 between the plates is reduced to F the original distance, what is the n'iagnitude of the new electric eld? Answer in units of N/C. 007 (part 1 of 2) A deuteron (a nucleus that consists of one pro- ton and one neutron) is accelerated through a 3.69 kV potential di'crence. How much kinetic energy does it gain? The mass of a proton is 1.6726? x 1027 kg, the mass of a neutron 1.67493 X 1027 kg and the charge on an electron 1.60218 X 1019 C. Answer in units of J. 008 (part 2 of 2) . What is its nal speed if it starts from rest? Answer in units of m/s. 009 Consider the setup where the potential func- tion is given by: V 2 43:2 + 23; 522. Find 5;; at the point: (2 m, 2 m, 5.8 In). Answer in units of N / C. 010 2 7. Ib, IIb, IIIb 5: X 8. Ib, IIa, IIIa 011 The plots in Figure 1 and Figure 2 show the X electric potential energy for a system of two interacting objects as a function r, which is the distance between the two objects. Figure Figure above shows a portion of long, neg- atively charged rod. You need to determine the potential difference VA - VB due to the Uel Uel charged rod. Use the convention that up is along the +y direction. Consider the following statements: Figure 1 Figure 2 Ia. Direction of the path is along the ty direction Figure 1 represents Ib.
