[" 3.State the condition under which a charged particle moving with the velocity 'v goes "],[" undeflected in a magnetic field B."]

Find the condition under which the charged particles moving with different speeds in the presence of electric and magnetic field vectors can be used to select charged particles of a particular speed.

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

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