Chapter 29, Problem 77(choose chapter or problem)
Consider an electron orbiting a proton and maintained in a fixed circular path of radius R 5 5.29 3 10211 m by the Coulomb force. Treat the orbiting particle as a current loop. Calculate the resulting torque when the electronproton system is placed in a magnetic field of 0.400 T directed perpendicular to the magnetic moment of the loop.
