In the figure particles 1 and 2 are fixed in place on an x axis, at a separation of L= 8.10 cm, Their charges are q, = te and 42 .27e Particle 3 with charge q, - +be is to be placed on the line between particles 1 and 2, so that they produce a net electrostatic force Fame on it. (al At what coordinate should particle 3 be placed to minimize the magnitude of that force? (b] What is that minimum magnitude? (a) Number 26. 7GE-24 Units (b] Number B.2E-24 Units N
