A proton travels at a speed of 5.0 107 m/s through a 1.0-T magnetic field. What is the magnitude of the magnetic force on the proton if the angle between the proton's velocity and the magnetic field vector is 30? (e = 1.60 10-19 C)

A) 2.0 10-12 N B) 4.0 10-14 N C) 2.0 10-14 N D) 4.0 10-12 N

Question 2

An s state (l = 0 ) energy level is split into two levels by an applied magnetic field. A photon of microwave radiation having frequency 60 GHz induces a transition between the two levels.

What is the magnitude of the applied magnetic field? (h = 6.626 10-34 J s, Bohr magneton = B = 9.27 10-24 J/T)
A) 0.34 T B) 2.1 T C) 1.2 T D) 2.8 T E) 13 T
