A charged particle is moving downward with an initial speed of 5 × 10^6 m/s when it encounters a uniform magnetic field that points east to west.

(a) If the initial force on the particle is to the north, is the particle positive or negative?

(b) If B = .25 T and the particle has a charge- to-mass ratio of 4 × 10^7 C/kg, what is the radius of the particle's path?

(c) What is the particle's speed after it has been in the field for 2 × 10^-4 seconds?
