A positively charged particle of mass 5.60 10-8 kg is traveling due east with a speed of 60 m/s and enters a 0.49-T uniform magnetic field. The particle moves through one-quarter of a circle in a time of 1.20 10-3 s, at which time it leaves the field heading due south. All during the motion the particle moves perpendicular to the magnetic field.

(a) What is the magnitude of the magnetic force acting on the particle?
1 N

(b) Determine the magnitude of its charge

    I thought I answered this.

    you know velocity as 60m/s,but it is also a quarter circle in the given time
    velocity=60=PI*radius/(2*timegiven)
    solve that for radius.

    a. centripetal force=mv^2/r and you know v, m, and r.
    but magnetic force has to be the same as centripetal force, so you know magnetic force.
    b. F=Bqv=centripetal force, solve for q.
