An electric charge `10^6muC` is placed at the origin (0, 0) of X-Y co-ordinate system. Two points A and B are situated at `(sqrt2, sqrt2)` and (2, 0) respectively. The potential difference between the points A and B will be

Options

A. `9 V`
B. zero
C. `2V`
D. `4.5 V`

Answer

B

Explanation

Distance of point a from origin
`=sqrt(2^(2)+0^(2))=2` units
Distance of point B from origin
`=sqrt(2^(2)+0^(2))=2` units
As point a & B are situated at equal distance, so `v_(A)=v_(B)`
