Homework Statement
One particle has a mass of 3.00 10-3 kg and a charge of +8.00 µC. A second particle has a mass of 6.00 10-3 kg and the same charge. The two particles are initially held in place and then released. The particles fly apart, and when the separation between them is 0.100 m, the speed of the 3.00 10-3 kg particle is 120 m/s. Find the initial separation between the particles.
Homework Equations
let the initial separation as r and final separation as d.
kq^2/r^2 = kq^2/d^2 + 1/2m1*V^2 + 1/2m2*V^2
is the the way to solve it? how can i determine the final velocity for the 6x10^-3 particle?
