The correct answer is D. Electric potential.
A vector is a quantity that has both magnitude and direction. Linear momentum, angular momentum, and electric field are all vectors. Electric potential is a scalar quantity, which means it only has magnitude.
Linear momentum is the product of an object’s mass and velocity. It is a vector quantity because it has both magnitude and direction. The direction of linear momentum is the same as the direction of velocity.
Angular momentum is the product of an object’s mass, radius, and angular velocity. It is a vector quantity because it has both magnitude and direction. The direction of angular momentum is perpendicular to the plane of rotation and points in the direction of the angular velocity vector.
Electric field is a vector quantity that describes the electric force per unit charge. The direction of the electric field is from positive charges to negative charges.
Electric potential is a scalar quantity that describes the electric potential energy per unit charge. It is a measure of the work done by an electric field in moving a charge from one point to another.
The electric potential is not a vector quantity because it does not have direction.
