Question

The electric potential (voltage) at a specific location is equal to the potential energy per unit charge a charged object would have if it were at that location. If the zero point of the voltage is at infinity, the numerical value of the voltage is equal to the numerical value of work done to bring in a unit charge from infinity to that location.
Select Show numbers and grid in the green menu, and drag one positive charge to the middle of the screen, right on top of two intersecting bold grid lines
What is the voltage 3 m away from the charge?
a. 3 V
b. 1 V
c. 9 V

The correct answer will be “4.5 V“.

Explanation:

Potential electric due to change,

As we know,

V₁ = 9

r₁ = 1

r₂ = 2

Now,
