prob05.problem Points:10 The figure shows a hollow cylindrical conductor with radii a = 1.2 cm and b = 4.7 cm which carries a current 6.0 A uniformly spread over its cross-section. Find the magnitude of the magnetic field at a distance of 3.2 cm from the axis. 3.75E-6 T First find the current density, J. Use the current density to find the current that is enclosed by a circle of radius 3.2 cm. Finally apply Ampere's Law to find the magnetic field. Submit Answer Incorrect. Tries 1/40 Previous Tries
Points:10 A 7 g particle carrying a charge of 59 μC enters a uniform 9 T magnetic field at a speed of 85 m/s and with an angle of 47° with respect to the field lines, as shown in the figure. For each of the following statements, determine whether it is true or false. Angle The field does a finite amount of work on the particle as the particle's trajectory is bent by the field. The x-component of the particle's velocity is unchanged as it passes through the B-Field. The Force on the particle is in the -z direction. The particle follows a circular path as the force is normal to the velocity. The particle's speed is unchanged as it passes through the B-Field. Submit Answer Tries 0/40
