Two particles, each having a mass m are ...

Two particles, each having a mass m are placed at a separation d in a uniform magnetic field B as shown in they have opposite charges of equal magnitude q. at time t =0, the particles are projectd towards each other,each with a speed v. suppose the coulomb force between the charges is switched off. (a) Find the maximum value `v_m` of the projection speed so that the two particles do not collide. (b) What would be the minimum and maximum separation between the particles if `v = v_m /2?` (c) At what instant will a collision occur between the particles if `v = 2v_m` ? (d) Suppose `v =2v_m` and the collision between the particles is completely inelastic. Describe the motion after the collision.
