Particle 1, with a charge q1 = 3.60 mC and a speed v1 = 862 m/s, travels at right angles to a uniform magnetic field. The magnetic force it experiences is unknown.
Particle 2, with a charge q2 = 53.0 mC and a speed (unknown), moves at an angle of 55.0° relative to the same magnetic field. Find (a) the strength of the magnetic field (b) the magnitude of the magnetic force exerted on particle 2 (c) the speed of particle 1 if the field and direction stayed the same but the force was unknown.
