Question

(a) Write the expression for the magnetic force acting on a charged particle moving with velocity v in the presence of magnetic field B.

Answer 1

(a) The force due to the magnetic field (B) acting on the charged particle moving with the velocity v is given by 

`vecF=q(vecvxxvecB)`

The direction of this force is given by the right-hand rule and it is perpendicular to the plane containing v and B.
