What is the magnitude of the magnetic force on the charge moving with velocity v3?

What is the magnitude of the magnetic force on the charge moving with velocity v1?

What is the magnitude of the magnetic force on the charge moving with velocity v2?

What is the direction of the magnetic force on the charge moving with velocity v2?

Centripetal force = Fmag Cyclotron frequency

Part a. Use A for i), B for ii) etc. Radius is proportional to v. Ans. B (ii)

Part b. Use A for i), B for ii) etc. Because r is proportional to v, the period is unchanged. Ans. A (i)

velocity

Use A for i), B for ii) etc. Same speed. Ans C (iii)
