Is a positive force attractive or repulsive?

The Coulomb force between two or more charged bodies is the force between them due to Coulomb’s law. If the particles are both positively or negatively charged, the force is repulsive; if they are of opposite charge, it is attractive.

Is attractive force positive or negative?

In general when the force is attractive, the potential energy is negative and as shown above force will be negative. In case of repulsion, with the same argument, the force will be positive.

Is repulsion a positive force?

According to Coulomb, the electric force for charges at rest has the following properties: Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges.

Is a negative force repulsive or attractive?

When the charges have opposite sign, the force is attractive (negative F), while if both charges have the same sign, the force is repulsive (positive F).

Why is positive force repulsive?

Coulomb Force — from Eric Weisstein’s World of Physics. The Coulomb force between two or more charged bodies is the force between them due to Coulomb’s law. If the particles are both positively or negatively charged, the force is repulsive; if they are of opposite charge, it is attractive.

Can a positive force be both attractive and repulsive?

The force is attractive or repulsive this can be defined on the basis that the two particles are positive or negative. … So the gravitational force cannot be negative and hence the gravitational force can only be attractive and cannot be repulsive. The correct answer for this problem is option B.

What does positive force mean?

Whenever a force is applied to an object, causing the object to move, work is done by the force. … Work can be either positive or negative: if the force has a component in the same direction as the displacement of the object, the force is doing positive work.

Is repulsive or attractive?

Repulsion is a movement between two charges that are identical or similar. The power that exists between two electrons (negative charge). Attraction is a force between two charges that are distinct or unlike.

What is a positive force?

When force and displacement are in the same direction, the work performed on an object is said to be positive work. Example: When a body moves on the horizontal surface, force and displacement act in the forward path. The work is done in this case known as Positive work.

Is negative potential attractive?

Remember the rule: Opposites attract; Likes repel. A positive charge would be repelled by something that already has a positive potential, while a negative charge would be attracted to the very same object.
