Question: As shown in Fig., charged particles are produced in a source S and accelerated through a potential difference = 200V. The particles enter a region of constant magnetic field B = 0.036T (directed out of the paper) and pass undeflected through two charged parallel plates spaced by 1.0cm. The voltage across the plates is 50V

a. Study the figure carefully. Are the particles positively or negatively charged? How do you know?

b. Prove that the particle velocity v = 1.39 × 105 m/s.

c. Find the mass-to-charge ratio of the particles, and from this identify the particle, choosing from the following list:

i. Electron.

ii. Alpha particle.

iii. Proton.

iv. None of the above
