In Fig., particles 2 and 4, of charge -e are fixed in place on a y axis, at y_(2) = -10.0 cm and y_(4) = 5.00 cm. Particles 1 and 3, of charge -e can be moved along the x axis. Particle 5, of charge +e, is fixed at the origin. Initially particle 1 is at x_(1) = -10.0 cm and particle 3 is at x_(3) = 10.0 cm (a) To what x value must particle 1 be moved to rotate the direction of the net electric force vec(F)_("net") on particle 5 by 60^(@) counterclockwise? (b) With particle 1 fixed at its new position, to what x value must you move particle 3 to rotate vec(F)_("net") back to its original direction ? |
