Question

Which equation is used to calculate the electric potential in an electric field from a point charge? V = kq over d squared V = kq over d V =delta U over q V = delta U over E

Answer 1

Answer:

The answer is V =delta U over q

Explanation:

Electric potential is defined as the magnitude of the electric field through the potential energy that a charge would have if placed at that point. Mathematically, the potential is defined with the following expression:

$V=\frac{E_{p} }{q}$

where:

V is the electric potential. Its unit is Julius by Coulomb (J/C).

Ep is the electric potential energy that has a charge

q is the charge

In the question Ep = ΔU

Answer 2

Answer:

The answer is V=kq/d

Explanation:

The electrostatic potential is defined in terms of work done in taking a unit positive charge from infinity to the point in question.

V=kq/d

Where d= distance from infinity to the point in question

k= constant of proportionality

q= attracting charge

The electric potential is measured in volts
