Question

What is the direction of the force acting on a charged particle $q$, moving with a velocity $\overrightarrow{v}$ in a uniform magnetic field $\overrightarrow{B}$?

Answer 1

As we know, for a charge moving with velocity, $\overrightarrow{v}$ in a field $\overrightarrow{B}$, the force experienced is given by, $\overrightarrow{F}=q(\overrightarrow{v}\times \overrightarrow{B})$

The direction of force will be perpendicular to the plane of the vector, $\overrightarrow{v}\times \overrightarrow{B}$
