An electron enters a uniform electric field with its velocity perpendicular to direction of electric lines of force, then

An electron enters an electric field with its velocity in the direction of the electric lines of force. Then

If an electron enters a magnetic field with its velocity pointing in the same direction as the magnetic field, then

If a proton is projected in a direction perpendicular to a uniform magnetic field with velocity v and and electron is projected along the line of force, what will happen to proton and electron?

Assetrion: If a proton and electron are placed in the same uniform electric field. They experience different acceleration Reason: Electric force on a test charge is independent of its mass

Assertion : In a uniform electric field electrons move in the opposite direction of electric field. Reason : This is because of the negative charge of an electron.

An electric dipole is placed in a uniform electric field. The net electric force on the dipole

A charged particle enters a uniform magnetic field perpendicular to it. The magnetic field

If electric field is uniform, then the electric lines of forces are :

Assertion A point charge produces a uniform electric field. Reason Due to a point charge, electric lines of forces are parallel and equidistant.

A proton and an electron are placed in a uniform electric field.
