Question

The electrons of a hydrogen atom move in a circular orbit of radius $5.3 	imes 10^{-11}$ meter with a speed of $2.2 	imes 10^{6} \mathrm{~m} / \mathrm{sec}$. The frequency $f$ in the orbit is\

Professor PC Thomas Classes · Answer

Frequency = no. of rotations/ sec $$ \begin{aligned} & =\frac{	ext { disance travelled in } 1 \mathrm{sec}}{	ext { circumfer coof circle }} \ & =\frac{\mathrm{v}}{2 \pi \mathrm{r}} \end{aligned} $$
