HW-3 due January 22 3-1 (HRW 22-1) In Fig. 22-30 the electric field lines on the left have twice the separation of those on the right. (a) If the magnitude of the field at A is 40 N/C, what is the magnitude of the force on a proton at A? (b) What is the magnitude of the field at B? F i g u r e 2 2 - 3 0 3-2 (HRW 22-13) In Fig. 22-36 , the three particles are fixed in place and have charges and . Distance . What are the (a) magnitude and (b) direction of the net electric field at point P due to the particles? F i g u r e 2 2 - 3 6 3-3 (HRW 22-25) In Fig. 22-45, two curved plastic rods, one of charge +q and the other of charge -q, form a circle of radius R = 8.5 cm in an xy plane. The x axis passes through both of the connecting points, and the charge is distributed uniformly on both rods. If q = 15.0 pC , what are the (a) magnitude and (b) direction (relative to the positive direction of the x axis) of
