Question:
A small aluminum ball with a charge of 13.45 C is moving northward at 3161 m/s. You want the ball to travel in a horizontal circle with a radius of 2.039 m, in a clockwise sense when viewed from above. Ignoring gravity, the magnitude of the magnetic field that must be applied to the aluminum ball to cause it to have this motion is B = 3.85310-1 T. What is the mass of the ball?
