An electron enters a region where magnetic field (B) and electric field (E ) are mutually perpendicular, then

An electron enter a region when magnetic field (B) and electric field (E) are mutually perpendicular, then

An electron is shot in steady electric and magnetic field E and magnetic field B mutually perpendicular. The magnitude of E is 1 volt // cm and that of B is 2 tesla. Now it happens that the Lorentz ( Magnetic ) force cancels with the electro static force on the electron, then the velocity of the electron is

An electron enters a region where electrostatic field is 20N//C and magnetic field is 5T . If electron passes undeflected through the region, then velocity of electron will be

In a region, electric field vecE and magnetic field vecB are mutually perpendicular. If a partical of charge q enters that region with velocity vecv normal to both the fields, under what condition does the direction of motion of the particle remain unchanged ?

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

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

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

An electron enters a region of space in which there exists an electric field 'E' and magnetic field 'B'. If the electron continues to move in the same direction with same velocity as before, the NOT possible case among the following is
