Electric Charges and fields part 2

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

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

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.

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.

STATEMENT-1 : Electric field lines start from a positive charge and terminate at a negative charge. and STATEMENT -2 : Electric field lines in free space are continuous curves.

A charge +Q at A as shown produces electric field E and electric potential V at D. If we now put charges - 3 Q and +Q at B and C, respectively, then the electric field and potential at D will be .

An isolated conducting sheet of area A and carrying a charge Q is placed in a uniform electric field E, such that the electric field is perpendicular to the sheet and covers all the sheet. Find out the charges appearing on its two surfaces.

A charge is moved in an electric field of a fixed charge distribution from point A to another point B slowly. The work done by external agent in doing so is 100 J . What is the change in potential energy of the charge as it moves from A to B ? What is the work done by the electric field of the charge distribution as the charge moves from A to B ?
