An electric field `(vec E) and a magnetic field (vec B)exist in a region . The fields are not perpendicular to each other.

In a certain region of space electric field E and magnetic field B are perpendicular ot each other and an electron enters region perpendicular to the direction of B and E both and moves undeflected, then velocity of electron is

In a certain region of space electric field E and magnetic field B are perpendicular to each other and an electron enters region perpendicular to the direction of B and E both and moves undeflected, then velocity of electron is (a) (|E|)/(|B|) (b) ExxB (c) (|B|)/(|E|) (d) E.B

In a certain region of space, electric field vecE and magnetic field vecB are perpendicular to each other. An electron enters in the region perpendicular to the direction of both vecB & vecE and moves undeflected. Find the velocity of electron.

An electromagnetic wave in vacuum has the electric and magnetic field vec E and vec B which are always perpendicular to each other. The direction of polarisation is given by vec X and that of wave propagation by vec k then
