The electric potential at a certain distance from a point charge can be represented by v. what is the value of the electric potential at twice the distance from the point charge?
the electric potential at a certain distance from a point charge can be represented by v. what is the value of the electric potential at twice the distance from the point charge?
at twice the distance, the electric potential is 4v.
at twice the distance, the electric potential is v/2.
at twice the distance, the electric potential is v/4.
at twice the distance, the electric potential is 2v.
at twice the distance, the electric potential remains v.

At twice the distance, the electric potential is V/2.

Explanation:

The electric potential at a certain distance d from a point charge q can be represented by V:

V = kq/d 1

Where q = charge ,d = distance between them, k = coulomb's constant.

When the distance is doubled d1 = 2d

Let V1 represent the electric potential after the distance have been doubled.

V1 = kq/2d = (kq/d)/2

V1 = V/2

Therefore, at twice the distance the electric potential is halved V1 = V/2

this a false

explanation:

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
