The plates of a Thomson q/m apparatus are 6.0 cm long and are separated by 1.2 cm.

Question:

The plates of a Thomson q/m apparatus are 6.0 cm long and are separated by 1.2 cm. The end of the plates is 30.0 cm from the tube screen. The kinetic energy of the electrons is 2.8 keV.

(a) If a potential of 25.0 V is applied across the deflection plates, by how much will the beam deflect?

(b) Find the magnitude of the crossed magnetic field that will allow the beam to pass through undeflected.
