Poistive and negative point charges of e...

Poistive and negative point charges of equal magnitude are kept at `(0, 0, a/2)` and `(0, 0, (-a)/(2))` respectively. The work done by the electric field when another poistive point charge is moved from `(-a, 0, 0)` to `(0, a, 0)` is

A

positive

B

negative

C

zero

D

depends on the path connecting the initial and final positions

Text Solution

Verified by Experts


The charges make an electric dipole, which will be uniform the equatorial plane of the dipole therefore potential at `A=` potential at `B=0`
`W=q(V_(A)-V_(B))=qxx0=0`
