PHYSICS 6B Ch.17 Worksheet www.clas.ucsb.edu/staff/vince/ 1) Find the magnitude of the electric force between two 1.00-C charges separated by 1.00m. 2) A charge q 1 = -5.4 μC is at the origin, and a charge q 2 = -2.2 μC is on the x axis at x=1.00. Find the net force acting on a charge q 3 = 1.6 μC located at x = 0.75m 3) An electron and a proton, initially separated by a distance d, are released from rest simultaneously. The two particles are free to move. When they collide, are they (a) at the midpoint of their initial separation, (b) closer to the initial position of the proton, or (c) closer to the initial position of the electron? 4) A charge q is to be placed at either point A or point B in the figure below. Assume points A and B lie on a line that is midway between the two positive charges. Is the net force experienced at point A (a) greater than,

Find the magnitude and direction of the force this field exerts on charges of (a) +2.80 μC and (b) -9.30μC 7) Two charges q 1 and q 2 , have equal magnitudes and are placed as shown in the figure below. The net electric field at point P is vertically upward. We must conclude that (a) q 1 is positive and q 2 is negative. (b) q 1 is negative and q 2 is positive. (c) q 1 and q 2 are both negative. (d) q 1 and q 2 are both positive. P q 1 q 2 E...
