TJ Physics PS 29 Due 2/25-26/2010 Note: Calculus is not required to solve these problems. 1. Three charges are arranged as shown in the figure below. In unit vector notation, calculate the force on the charge at the origin. 2. Three charges are arranged as shown in the figure below. In unit vector notation, calculate the force on the 6.00 nC charge. 3. Three small charges are arranged as shown in the figure below. Determine the value of Q (positive or negative and magnitude) that will make the net force on the 25 nC charge point entirely in the positive Y direction. 0.300 m 0.100 m 6.00 nC 5.00 nC -3.00 nC X Y 6.00 nC X Y 0.500 m 0.500 m 2.500 m 3.00 nC -3.00 nC Y X Q 25 nC 45 nC 0.05 m 0.05 m 0.05 m

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...
