Which of the following particles will have minimum frequency of revolution when projected with the same velocity perpendicular to a magnetic field?
A. Electron
B. Proton
C. He+
D. Li+
Answer :
Formula used: Time period of revolution of a particle is given by
In the above options Electron is light weight particle and Li+ has highest weight compared to other particles in the options given. Frequency f is inversely proportional to mass m. So Li+ will have minimum frequency of revolution. So option D is correct.
