Question

The work done in bringing at a unit positive charge from infinity distance to a point at distance $x$ from a positive charge $Q$ is $W$. Then the potential $\phi$ at that point is

• A. $\frac{WQ}{X}$
• B. $W$
• C. $\frac{W}{Q}$
• D. $WQ$

Answer 1

Answer: (B)

$W$

Answer 2

Electric potential at a point in an electric field is defined as the potential energy per unit charge, and which is equal to work done in bringing a unit positive charge from infinity to that point.
$\therefore \phi= W$
