Question

If the expression in vector form, for the magnetic force $\overrightarrow{F}$ acting on a charged particle moving with velocity $\overrightarrow{V}$ in the presence of a magnetic field $\overrightarrow{B}$ is given by $\overrightarrow{F}=a\ast q\overrightarrow{v}\times \overrightarrow{r}$. Find a.

Answer 1

For a a charged particle moving with a velocity v in a magnetic field B
$\overrightarrow{F}=q\overrightarrow{v}\times \overrightarrow{r}$
