Lorentz Force and Effect OF Both Electric Field and Magnetic Field

Assertion (A),If electrons travel undefeccted by the electric field E and magnetic field B then the velocity of electrons is given by V=e/b . Reason (R ) : When both electric and magnetic field are applied simultaneously on electron beam. If force due to electric field is equal and opposite to force due to magnetic field then they travel undeflected.

A force vecF acting on an electric charge q, in presence of an electromagnetic field, moves the charge parallel to the magnetic field with velocity vecv . The vecF is equal to (where vecE and vecB are electric field and magnetic field respectively)

Assertion (A) Electric force and magnetic force are jointly called electromagnetic force. Reason. (R) Electric field can produce magnetic field and magnetic field can produce electric field.

A He^(2+) at rest experiences an electromagnetic force. Then (where E is electric field and is B magnetic field)

The force acting on a charge q in both electric and magnetic field, stimulateneously is

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

Relation between energy density of electric field and magnetic field in em wave.

Can a photon be deflected by an electric field ? By a magnetic field ?

When light propagates in vacuum there is an electric field and a magnetic field. These fields
