Unformatted text preview: 4B Homework 04 *Question 1 How much work in joules is required to set up the four-charge configuration of Fig. 24-46 if q = 7.57 pC, a = 44.6 cm, and the particles are initially infinitely far apart and at rest? Figure 24-46 Number-2.99E-12 Units J The number of significant digits is set to 3; the tolerance is +/-2% *Question 2 When an electron moves from A to B along an electric field line in Fig. 24-29, the electric field does 3.44 x 10-19 J of work on it. What are the electric potential differences (a) V B- V A , (b) V C- V A , and (c) V C- V B ? Figure 24-29 (a) Number 2.15 Units V (b) Number 2.15 Units V (c) Number 0 Units V Answer a1: the number of significant digits is set to 3; the tolerance is +/-2% Answer b1: the number of significant digits is set to 3; the tolerance is +/-2% Answer c1: the number of significant digits is set to 1; the tolerance is +/-2% *Question 3 In Figure 24-52, a charged particle (either an electron or a proton) is moving rightward between two parallel charged plates...
