What is the direction of force acting on a charged particle q, moving with a velocity in a uniform magnetic field?

What is the direction of force acting on a charged particle ‘q’ moving with a velocity overset rarr v in a unifom magnetic field overset rarrb ?

What will be the path of a charged particle moving along the direction of a uniform magnetic field?

Write a relation for the force vecF acting on a charge carrier q moving with velocity vecv through the magnetic field vecB in vector notation. Using this relation, deduce the conditions under which this force will be minimum?

Write a relation for the force vecF acting on a charge carrier q moving with velocity vecv through the magnetic field vecB in vector notation. Using this relation, deduce the conditions under which this force will be maximum?

Define magnetic field. Write an expression for force on a charge q moving with velocity vecv in a region having uniform magnetic field strength vecB . How does the speed change as the charge moves? Under what circumstances the force vecF will be zero and maximum? also obtain S.I. unit of the strength of magnetic field. Also give dimensional formula of B.
