A charged particle moves with velocity vecv in a uniform magnetic field vecB . The magnetic force experienced by the particle is

A charge q moving in a straight line is accelerated by a potential difference V. It enters a uniform magnetic field B perpendicular to its path. Deduce in terms of V an expression for the radius of the circular path in which they travel?

A particle of charge ‘q’moves with a velocity v at an angle ‘0’ to a magnetic field ‘B’. What is the force experienced by the particle ?

A proton and an alpha particle of the same velocity enter in turn a region of unifrom magnetic field acting a plane perpendicular to the magnetic field. Deduce the ratio of the radii of the circular paths described by the particles. Explain why kinetic energy of the particle after emerging from the magnetic field remains unaltered.

A particle with charge q moving with a velocity v in the plane of the paper enters a uniform magnetc field B, acting perpendicular to the plane of the paper. Deduce an expression for the tie period of the charge, as it moves in a circular path in the field. Why does the kinetic energy of the charge not change, while moving in the magnetic field?

A stream of elelctrons travelling with speed vms^-1 at right angles to a uniform magnetic field 'B' is deflected in a cirucular path of radius 'r'. Prove that (e)/(m)=v/(rB) .
