A positively charged particle of mass 6.2*10-8 kg is traveling north with a speed of 61 m/sand enters a 0.33 T uniform magneticfield. The particle moves through one-quarter of a circle in a timeof 3.0*10-3 s, at which time it leaves the fieldheading east. All during the motion theparticle moves perpendicular to the magnetic field.
(a) Determine the magnitude and charge of the particle
(b) What is the direction of the uniform magnetic field
