two particles labelled A and B. Particle A has mass m = 0.001 kg and charge q = +5.0*10^-6C. particle B has mass m = 0.002 kg and the same charge q = +5.0*10^-6C. the two particles are initially held in plae (stationary) and then released. the particles fly apart and when the seperation between then is r(f)= 0.15m, the speed of particle A is v(Af)= 105m/s. ( note: inside the "system" that includes both particles the two principles of conservation of energy and momentum are both applicable.) a. find the magnitude and direction of the velcity of particle B; that is v(Bf). b. find the initial seperation r(o) between the particles.
