help please show detailed instructions on white sheet of paper i will give upvote for helping me solve this thank you

3. A mixture of two kinds of particles is launched with an initial velocity of u = +Voj. Both particles carry equal charge magnitude |q|. While in the region of uniform magnetic field B = +Boi, one of the particles traces the green path, and the other moves along the red curve as shown in the figure below. Also, the particles exit rightmost side of the region of magnetic field. a. What is the charge sign of the particle that traverses the green curve? b. What is the charge sign of the particle that traverses the red curve? c. Let m, and m, be the masses of the particles traversing the green and the red curves, respectively. What is my/m,? d. How much time will it take for the two particles to travel within the region of uniform magnetic field? B = +Boi b/2 ZA b X
