Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.

What is the speed of an object at a given moment?

)consider two positively charged particles, one of charge q0 (particle 0) fixed at the origin, and another of charge q1 (particle 1) fixed on the y-axis at (0,d1,0). what is the net force f⃗ on particle 0 due to particle 1?
