Repeat part (c) of Problem 26, but now assume the particle’s velocity is along the -x direction at t = 0.

(reference problem 26)

A particle of charge and mass kg moves at a speed of 2000 m/s, and its velocity vector lies in the x–y plane. There is a magnetic field of magnitude 0.88 T along the +z direction. The magnetic force on the particle causes the particle to move in a circle that lies in the x–y plane. (a) Find the radius of this circle. (b) Find the period of the motion. (c) If the particle is moving parallel to +y at t = 0, is the circular motion clockwise or is it counterclockwise as viewed from along the +z axis?
