Work Done To Move A Charge In An Electrostatic Field

The work done in carrying a point charge form one point to another in an electrostatic field depends on the path along which the point charge is carried.

Consider the three statements in context of electrostatic field lines. STATEMENT-1 : Electrostatic field lines are continuous curves in space. STATEMENTS-2 : Electrostatic field lines are always perpendicular to equipotential surface. STATEMENT-3 : A charge when released in electrostatic field moves along electrostatic field lines.

Assertion(A): A point charge q is rotated along a circle around another point charge Q .The work done by electric field on the field on the rotating charge in half revolution is zero. Reason (R ) :No work is done to move a charge on an equipotential line or surface.

Potential difference between any two points B and A in an electrostatic field is the amount of work done in carrying ………… from …………. to ………………….. .

The work done to move a charge along an equipotential from A to B

Work done by an electrostatic field in moving a given charge from one point to another …… upon the chosen.

Show that the tangential component of electrostatic field is continuous from one side of charged surface to another. [Hint : use the fact that work done by electrostatic field on a closed – loop is zero.]

Statement-1. For a charged particle moving from pont P to point Q , the net work done by an electrostatic field on the particle is independent of the path connecting point P to point Q Statement-2. The net work done by a conservatie force on an object moving along a closed loop is zero.

Which among the following statements is true about the work done in bringing a unit positive charge from point P to Q in an electrostatic field ?
