Question

A charged particle of mass m = 7.2X10-8 kg, moving with constant velocity in the y-direction enters a region containing a constant magnetic field B = 1.8T aligned with the positive z-axis as shown. The particle enters the region at (x,y) = (0.99 m, 0) and leaves the region at (x,y) = 0, 0.99 m a time t = 439.0 ?s after it entered the region. 1. With what speed v did the particle enter the region containing the magnetic field? 2. What is Fx, the x-component of the force on the particle at a time t1 = 146.3 ?s after it entered the region containing the magnetic field. 3. What is Fy, the y-component of the force on the particle at a time t1 = 146.3 ?s after it entered the region containing the magnetic field. 4. What is q, the charge of the particle? Be sure to include the correct sign.
