A charged particle moving with a uniform velocity` vecv `enters a region where uniform electric and magnetic fields` vecE and vecB` are present. It passes through the region without any change in its velocity. What can we conclude about the magnitude of `vecE` and `vecB`?

A charged particle moving with a uniform velocity vecv enters a region where uniform electric and magnetic fields vecE and vecB are present. It passes through the region without any change in its velocity. What can we conclude about the relative direction of vecE , vecv and vecB?

A charged particle moves with velocity vecv in a uniform magnetic field vecB . The magnetic force experienced by the particle is

A positively charged particle moving due east enters a region of uniform magnetic field directed vertically upwards. The particle will

A charge q moves in a region, where electric field vecE and magnetic field vecB both exist, then the force on it is

When a charged particle moving with velocity vecv is subjected to a magnetic field of induction vecB , the force on it is non-zero. This implies that

What is the direction of force acting on a charged particle q, moving with a velocity in a uniform magnetic field?

A charged particle is released from rest in a region of steady and uniform electric and magnetic fields which are parallel to each other . What will be the nature of the path followed by the charged particle?
