The potential difference `V_(A)-V_(B)` will be:

Options

A. Positive
B. Negative
C. Zero
D. Cannot be determined

Answer

A

Explanation

Positive
Explanation: Let distance from Q to A and B be `r_(A) and r_(B)` respectively
`V_(A)=(+Q)/(4pi epsi_(0)r_(A))`
and `V_(B)=(+Q)/(4pi epsi_(0)r_(B))`
`V_(A)=V_(B)=(+Q)/(4pi epsi_(0))((1)/(r_(A))-(1)/(r_(B)))`
`r_(A) lt r_(B)`
`:. V_(A)-V_(B)` is positive.
