Question

In Exercise. 11 obtain the frequency of revolution of the electron in its circular orbit. Does the answer depend on the speed of the electron? Explain.

Answer 1

Frequency in Exercise 11,
υ = \(\frac { qB }{ 2πm }\)
= \(\frac{1.6 \times 10^{-19} \times 6.5 \times 10^{-4}}{2 \times \pi \times 9.1 \times 10^{-31}}\)
= 18 MHz
