Page < > of 8 ZOOM Do BOTH of Problems 7 and 8 Problem 7: (7 pts) A circular loop with 80 turns and a radius of 50.0crd is placed in a 0.750T magnetic field. A constant 4.004 current is run counter-clockwise through the loop. The magnetic field is initially in the plane of the leap as shown. (a) (2 pts) What is the initial torque on the loop from the magnetic field? (b) (2 pts) What is the initial magnetic potential energy of the loop? (0) (3 pts) Through what angle must the loop be rotated to reach a torque of 35.0Nm? Problem 8: (7 pts) An electron circulates in an unknown, constant magnetic field oriented out of the page with an unknown velocity. The radius of curvature of the electron is 5.52m. The magnitude of the magnetic force on the electron is 5.00x10-16N. The electron is circulating in a circle on the page. (a) (6 pts) What is the kinetic energy of the particle? (b) (1 pt) Which way does it turn? Counter-clockwise or clockwise?
