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 ?

When a particle carrying charge q enters a unifrom electric field with a velocity vecv normal to the field, the nature of the path of that particle becomes parabolic-discuss.

Statement I: The electric field vecE and the magnetic field vecB are mutually perpendicular at a point in the electromagnetic wave. Statement II: Electromagnetic waves are transverse waves.

A particle of mass 'm' and carrying a charge q enters with a velocity 'v' perpendicular to a uniform magnetic field. The time period of rotation of the particle

A charge q moves with velocity vecv at an angle theta to a magnetic field vecB . What is the force experienced by the particle?

A uniform electric field and a uniform magnetic field are acting along the same direction in a certain region. If an electron is projected in the region with a velocity along the direction of fields, then

A particle of charge q moves with a velocity vecv=ahati+bhatj in magnetic field vecB=chati+dhatj . The force acting on the particle has magnitude F. Them

A particle with charge q is moving with a velocity vecv in a magnetic field vecB . If the force acting on the particle is vecF then,

(C) Carry equal amount of energy by dividing average energy of the wave between them. (D) The ratio of amplitude of these fields is equal to the speed of light.

In a region, a uniform electric field and a uniform magnetic field are acting in the same direction. An electron is shot along the directio of the fields. What change will be obsverved in the magnitude and direction of the velocity of that electron ?
