A schematic diagram showing a velocity selector coupled to a deflection chamber. On the left, a horizontal beam line enters through a narrow slit into a rectangular box labeled Velocity Selector. Inside the box, four evenly spaced downward vertical arrows are labeled E, and five evenly spaced crossed-circle icons represent a magnetic field labeled B. A straight horizontal line continues through an exit slit into a larger square region labeled Deflection Chamber. The deflection chamber contains nine evenly spaced crossed-circle icons representing a uniform magnetic field labeled B. Inside the deflection chamber, a dashed semicircular path bends upward from the entrance slit, forming an arc with a radial arrow pointing from the center of the arc to the path labeled R. No other labels, lines, text, or axes appear.
A velocity selector coupled to a deflection chamber.
A beam containing two types of positive ions, Type 1 (charge \(q\), mass \(m\)) and Type 2 (charge \(2q\), mass \(4m\)), enters a velocity selector with electric field magnitude \(E\) and magnetic field magnitude \(B\). The ions that emerge undeflected from the velocity selector then enter a deflection chamber containing a uniform magnetic field of the same magnitude \(B\) directed perpendicular to their velocity. If the undeflected Type 1 ions follow a semicircular path of radius \(R\) in the deflection chamber, what is the radius of the semicircular path followed by the undeflected Type 2 ions?
