Is positive force attractive?

If the particles are both positively or negatively charged, the force is repulsive; if they are of opposite charge, it is attractive. … Like the gravitational force, the Coulomb force is an inverse square law.

Are attractive force positive or negative?

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).

Can positive force be attractive or repulsive?

Regarding force (c)A positive force can be both attractive and repulsive in nature. Explanation: The force is repulsive if the particles are both positively or negatively charged; it is attractive if they are of opposite charge.

Is a negative force attractive?

9. When they are connected with a wire, the spheres will evenly divide the total charge. Also, an attractive force is negative, and a repelling force is positive.

What force is very attractive?

gravitation, gravitational attraction, gravitational force, gravity. (physics) the force of attraction between all masses in the universe; especially the attraction of the earth’s mass for bodies near its surface. magnetic attraction, magnetic force, magnetism.

What is 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.

What does positive force mean?

This means that to do work, in physics, you need to push or pull on something, and while pushing or pulling, you have to make it move. … Now, if the force and displacement happen to be in the same direction, that’s when we say work done is positive, it’s a positive number.

Why is negative potential attractive?

U=−rGMm​. This is a negative value for two reasons; the force acting between them is attractive, and the zero of potential energy is at infinite separation. This is a negative result if the force between the two charges is attractive (they are opposite) and positive if it is repulsive (the charges are similar).

Is electromagnetic force attractive or repulsive?

Electromagnetism is both an attractive and repulsive force between particles with a property called charge, which come in two varieties – positive and negative. Objects of like charge will have a repulsive effect on each other, while objects of unlike charges will have an attractive effect.

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.

Is gravitational force attractive or repulsive?

Gravitational force -an attractive force that exists between all objects with mass; an object with mass attracts another object with mass; the magnitude of the force is directly proportional to the masses of the two objects and inversely proportional to the square of the distance between the two objects.
