Assuming we know the charge & mass of the ion, as well as the radius of curvature in the separation chamber. Which Voltage (V1 or V2) will we need to make use of to determine the strength of the uniform magnetic field (B2) in the separation chamber. Also Assume we know B1.

Record your voltage selection, as well as which physics principle applies to the motion in the separation chamber. Using the numbers on the data sheet, match the physics principle.

voltage: _ principle: _
