Under what conditions is the force acting on a charged particle moving through a uniform magnetic field is maximum.

Explanation

`F_(m)= q (vec(v) xx vec(B))`
`F_(m)= q v B sin theta`, F will be maximum if `sin theta=1 or theta= 90^(@)`. Therefore force will maximum if `vec(v) and vec(B)` are perpendicular to each other.
