General Physics 2 Final Review Spring 2019 Wilberforce Problem 1 A 2.0-C charge moves with a velocity of ( ) m/s and experiences a magnetic force of ) N. The x component of the magnetic field is equal to zero. Determine the z component of the magnetic field. Problem 2 The figure shows the orientation of a rectangular loop consisting of 80 closely wrapped turns each carrying a current I . The magnetic field in the region is ( ) mT. The loop can turn about the y axis. If = 30 , a = 0.40 m, b = 0.30 m, and I = 8.0 A, what is the magnitude of the torque exerted on the loop?

Problem 3 What is the magnitude of the magnetic field at point P if a = R and b = 2 R ? Problem 4 The figure shows a cross section of three parallel wires each carrying a current of 20 A. The currents in wires A and B are out of the paper, while that in wire C is into the paper. If the distance R = 5.0 mm, what is the magnitude of the force on a 2.0-m length of wire A?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
