The electric potential at a distance d from a point charge q in air of permittivity eo is expressed as?
q2 ÷ 4πeod
q2 ÷ 4πeo
q ÷ 4πeod2
q ÷ 4πeod
q ÷ 4πeo2d
Correct answer is D
The electric potential at a point in an electric field is defined as the amount of work done in moving a unit positive charge from infinity to that point against the action of the field.
V = \(\frac{Q}{4 π∈r}\)
