***hurry***which equation is used to calculate the electric potential in an electric field from a point charge? v = k q/d^2 v = k q/d △v = △u/q △v = △u/e

Answer : The correct option is,

Explanation :

Electric potential : It is defined as the amount of work needed to move a unit of positive charge from a point charge (reference) to a specific point inside the field.

Mathematically it is written as :

where,

V = electric potential

q = electric charge

d = distance between the reference point and the specific point

k = = k = constant

Hence, the formula is,

the arctic is a region of the planet, north of the arctic circle, and includes the arctic ocean, greenland, baffin island, other smaller northern islands, and the far northern parts of europe, russia (siberia), alaska and canada.

i think they are all correct

explanation:

they seem good
