A particle having charge q moves with a velocity v through a region in which both an electric field `vecE` and a magnetic field B are present. The force on the particle is

Write the expression for the force vecF , acting on a charged particle of charge q moving with a velocity vecv in the pressure of both electric field vecE and magnetic field vecB . Obtain the condition under which the particle moves undeflected through the fields.

A charge q moves region in a electric field E and the magnetic field B both exist, then the force on its is

A charge particle travels along a straight line with a speed v in region where both electric field E and magnetic field b are present.It follows that

A charged particle is moved along a magnetic field line. The magnetic force on the particle is

In a region where both non-zero uniform electric field and magnetic field coexist, the path of a charged particle

A particle of charge q and mass m is moving along the x-axis with a velocity v and enters a region of electric field E and magnetic field B as shown in figures below. For which figure the net force on the charge may be zero?
