The magnetic force $\mathrm{q}[\mathrm{v} \times \mathrm{B}]$ is

The magnetic force $\mathrm{q}[\mathrm{v} \times \mathrm{B}]$ is
  1. parallel to both $\mathrm{v}$ and $\mathrm{B}$
  2. perpendicular to $\mathrm{v}$
  3. perpendicular to both $\mathrm{v}$ and $\mathrm{B}$
  4. parallel to B

Solution

The magnetic force is perpendicular to both $\mathrm{v}$ and $\mathrm{B}$. $\mathrm{F}=\mathrm{q}[\mathrm{v} \times \mathrm{B}]$
