Explanation
By Fleming's left hand rule
The component of velocity perpendicular to H will make the motion circular while that parallel to H will make it move along a straight line. The two together will make the motion helical.
When particle enters at angles other than 0° or 90° or 180°, path followed is helix.
A moving charge gains energy in electric field only because in magnetic field energy remains constant.
Since force is perpendicular to direction of motion, energy and magnitude of momentum remains constant.
The deflection produced by the electric field may be nullified by that produced by magnetic field.
When particle enters perpendicularly in a magnetic field, it moves along a circular path with constant speed.
The charged particle moving in a magnetic field does not gain energy. However, the direction of its velocity changes continuously. Hence momentum changes
Apply Fleming's left hand rule
Here magnetic force is zero, but the velocity increases due to electric force.
When field is parallel to the direction of motion of charge, magnetic force on it is zero.
Charged particles deflect in magnetic field.
Particles entering perpendicularly, hence they will describe circular path. Since their masses arc different so they will describe path of different radii.
