If a unit positive charge is taken taken from one point to another over an equipotential surface, then

If a unit positive charge is taken from one point to another over an equipotential surface ,then

When a positive q charge is taken from lower potential to a higher potential point, then its potential energy will

When a positive q charge is taken from lower potential to a higher potential point, then its potential energy will

If n positive integers taken at random are multiplied together.

The potential produced by a point charge is V = kQ// r . Use this information to determine the shape of equipotential surface ?

Assertion: For a point charge concentric spheres centered at a location of the charge are equipotential surfaces. Reason : An equipotential surface is a surface over which potential has zero value.

An object is taken from a point P to another point Q in a gravitational field:

A point charge of 5C is placed at point P (as shown in figure). A unit positive charge is taken from A to B along the circular path shown, then the net work done by electrostatic force is : [O is the centre of the circular path] [Where k=9xx10^9 Nm^2//C^2 ]

Nature of equipotential surface for a point charge is

The work done in bringing a unit positive charge from infinite distance to a point at distance x from a positive charge Q is W. Then the potential phi at that point is
