Unformatted text preview: Determine, in unit vector notation, the initial acceleration of the 90.0 nC charge if the objects are released from rest. 5. #13 in Chapter 21 of HR&W In Fig. 21-26, particle 1 of charge +1.o uC and particle 2 of charge -3.0 uC are held at separation L = 10.0 cm on an x axis. If particle 3 of unknown charge q3 is to be located such that the next electrostatic force on it from particles 1 and 2 is zero. . 6. #33 in Chapter 21 of HR&W In Fig. 21-3 six charged particles surround particle 7 at radial distances of either d = 1.0 cm or 2d as drawn. The charges are q1 = +2e, etc TJ Physics 1 Group 2 2/10 Y X m 1 = 8.00 g q = -75.0 nC m 2 = 5.00 g q = 75.0 nC m 3 = 2.50 g q = 90.0 nC 4.00 cm 3.00 cm...
