Positive and negative charges of `1 muC` each are placed at two points as shown in the figure. Find the potential difference between A and B

Answer

`3000` volt

Explanation

`{:(V_(A)=(KQ)/(2)-(KQ)/(3),|),(V_(B)=(KQ)/(3)-(KQ)/(2),):}V_(A)-V_(B)=2((KQ)/(2)-(KQ)/(3))`
`=9xx10^(9)xx10^(-6)(1-2/3)=3000` volt
