Two points A and B located in diametrically opposite directions of a point charge of +2`muC` at distances 2.0 m and 1.0 m respectively from it. Determine the potential difference `V_(A)-V_(B)`.

A

`3xx10^(3)V`

B

`6xx10^(4)V`

C

`-9xx10^(3)V`

D

`-3xx10^(3)V`

Text Solution

Verified by Experts

The correct Answer is:
C
Here, `q=2muC=2xx10^(-6)` C , `r_A=2m , r_B=1m`
`therefore V_A-V_B=q/(4piepsilon_0)[1/r_A-1/r_B]`
`=2xx10^(-6)xx9xx10^(9)[1/2-1/1]V`
`=-9xx10^3` V
