Question

***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 1

choice 2 is the answer

Answer 2

Answer : The correct option is,
`V=k(q)/(d)`

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 :

`V=k(q)/(d)`

where,

V = electric potential

q = electric charge

d = distance between the reference point and the specific point

k =
`(1)/(4\pi \epsilon_o)` = k = constant

Hence, the formula is,
`V=k(q)/(d)`
