Question: (4) An electron in a hydrogen atom may move counter-clock wise in a circular orbit of radius R about the proton due to Coulomb's force.

(4) An electron in a hydrogen atom may move counter-clock wise in a circular orbit of radius R about the proton due to Coulomb's force. Suppose such an atom is placed in a uniform magnetic field B, with the plane of the orbit at right angles to B. Ignore the effect of gravity and assume the orbit radius R does not change due to the applied magnetic field.(a) Calculate the frequency of revolution of the orbiting electron. (b) Compute the magnetic torque on the electron. (5-points) H
