In Fig., particles 1 and 2 are fixed in place on an axis, at a separation of L = 6.00 cm. Their charges are q_(1) = +e and q_(2) = -27e. Particle 3 with charge q_(3) = +4e is to be placed on the line between particles 1 and 2 , so that they produce a net electrostatic force vec(F)_("3,net") on it. (a) At what coordinate should particle 3 be placed to minimize the magnitude of that force ? (b) What is that minimum magnitude ? |
