A 3.0 µg charged particle carrying -25 µC is injected along the +x direction into a velocity selector. The velocity selector is composed of a parallel plate capacitor with 1 kV of potential between two plates separated by 1 cm and pair of solenoids with 3000 turns per cm separated by 2 mm. On the opposite side of the velocity selector from the injection site is a uniform 1.5 T magnetic field pointing in the +z direction. Draw a diagram of this device with direction of electric fields, magnetic fields, electric force, and magnetic forces clearly labeled. At what velocity must the particle be injected to pass straight through the velocity selector and exactly (direction and quantitative description) what will its path be once it enters the 1.5 T magnetic field?
