Electric charges and fields

The work done in moving an electric charge q in an electric field does not depend upon

STATEMENT-1 : A stationary electric charge produce electrostatic field and this field exterts electrostatic force on other charge. STATEMENT-2 : Theoritically electric field is found upto infinite distance from a point charge. STATEMENT-3 : An electron is a point charge.

If a charged particle goes unaccelerated in a region containing electric and magnetic fields,

If a charged particle goes unaccelerated in a region containing electric and magnetic fields,

A charged particle goes undeflected in a region containing electric and magnetic field. It is possible that

What potential difference must be applied to produce an electric field that can acceleration an electric charge to one length the velocity of light ?

A sphere carries a uniformly distributed electric charge. Prove that the field inside the sphere is zero

Assertion Due to two charges electric field and electric potential cannot be zero at some point simultaneously. Reason Field is a vector quantity and electric potential is a scalar quantity

Assertion: A point charge is brought in an electric field. The field at a nearby point will increase, whatever be the nature of the charge. Reason: The electric field is independent of the nature of charge.
