In the electric field of a point chargde...

In the electric field of a point chargde `q`, a cetrain charge is carried from point `A` to `B, C, D` and `E`. Then the ork done

A

is least along the path `AB`

B

is least along the path `AD`

C

is zero along all the paths `AB, AC, AD and AE`

D

is least along `AE`

Text Solution

Verified by Experts

The correct Answer is:
C
`ABCDE` is an equipotential surface, on equipotential surafce no work is done in shifting a charge from one place to another.

Which of the following statement(s) is/are correct? If the electric field due to a point charge varies as r^(-2.5) instead of r^(-2),then the Gauss law will still be valid. The Gauss law can be used to calculate the field distribution around an electric dipole. If he electric field between two point charges is zero somewhere,then the sign of the two charges is the same. The work done by the external force is moving a unit positive charge from point A at potential "V_(A)" to point B at potential "V_(B)" is,(V_(B)-V_(A))

In an uniform electric field of strength E, a charge particle Q moves point A to point B in the direction of the field and back from B to A. Calculate the ratio of the work done by the electric field in taking the charge particle from A to B and from B to A.
