Question

A 8 kg particle carrying a charge of 75 uC enters a uniform 8 T magnetic field at a speed of 48 m/s and with an angle of 67o with respect to the field lines, as shown in the figure. Answer the following questions: (Select T-True, F-False, If the first is T and the rest F, enter TFFFF).

A) The initial force on the particle is in the +x direction.
B) The field does a finite (non-zero) amount of work on the particle as the particle's trajectory is bent by the field.
C) The particle's speed varies as it passes through the B-Field.
D) The x-component of the particle's velocity is unchanged as it passes through the B-Field.
E) The particle follows a helical path.
