Work done by the electric force in a moving charge:
Magnetic force on moving charge:
The kinetic energy of the ions is equal to the work done by the electric force.
|W| = |K|
qΔV = (1/2)mv2
v = (2qΔV/m)(1/2)
The net force on the ions is due to the magnetic force.
Ions having equal charges but masses of M and 2M are accelerated through the same potential difference and then enter a uniform magnetic field perpendicular to their path. If the heavier ions follow a circular arc of radius R, what is the radius of the arc followed by the lighter?
