Physics Chapter on Magnetic Fields

The kinetic energies of the proton and deuteron are equal, represented by Kp:Kd = 1:1.

Adjust the thumb, forefinger, and middle finger such that forefinger points to the magnetic field and middle finger points to the velocity; the thumb then indicates the direction of the magnetic force.

The radius of the circular path for the deuteron is also 10 cm.
