Solve the all parts of given question:
Question: A particle of charge 24 microC and mass 1.4 x10-15 kg moves at a speed of 2240 m/s, and its velocity vector lies in the xy plane. There is a magnetic field of magnitude 0.87 T along the +z direction. The magnetic force on the particle causes the particle to move in a circle that lies in the xy plane.
Part A: Find the radius of this circle.
Part B: Find the period of the motion.
