Velocity of a charged particle can remain unchanged. If

Give the expression for velocity of a charged particle in a cyclotron.

The velocity of a charged particle moving in a magnetic field perpendicular to it is

Show that in SHM the ratio of acceleration and displacement of a particle always remains unchanged.

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 ?

Statement 1: A magnetic field independent of time can change the velocity of a charged particle. Statement 2: It is not possible to change the velocity of a particle in a magnetic field as magnetic field does no work on the charged particle.

Does the quality of water stored in a reservoir remain unchanged ?
