Question 1. A proton of charge + 1.6 x 10^(-19) C and mass 1.67 x 10(-27)kg is introduced into a region of B = 1.5 T with an initial velocity of 1.25 x 10^6 m/s perpendicular to B. What is the radius of the proton's path?
Question 2. A coil 17 cm in diameter and wound with 12 turns of wire is placed with the plane of the coil at right angles to a magnetic field of .038 T. What emf is induced in the coil if the field is halved in 0.54s. ?
Question 3. A capacitor C = 4.7 nF is connected across a 2.5 mH inductor. What is the natural oscillation frequency of the combination?
