Write the relation for the force `vecF` acting on a charge carrier q moving with a velocity `vec v` through a magnetic field `vec B` in vector notation. Using this relation, deduce the conditions under which this force will be
(i) maximum (ii) minimum. Under what condition will it move in (i) a circular path and (ii) a helical path?
