Is electrostatic force always attractive?
The electrostatic force is a very large force. There are two types of charges: positive charges and negative charges. Like charges repel each other and unlike charges attract each other. Therefore, electrostatic forces are not always attractive.
How do you know if the force is attractive or repulsive?
If both the interacting particles are positively or negatively charged, then the force is repulsive. If both the interacting particles are of opposite charges then the force is attractive in nature.
What is electrostatic attraction and repulsion?
Electrostatic Attraction and Repulsion. The attraction and repulsion of electrostatically charged bodies for each other, shown when charged with electricity. If charged with electricity of the same sign they repel each other. If with opposite they attract each other.
Why electrostatic force is attractive as well as repulsive in nature?
The electrostatic force can be attractive or repulsive because the sign of the charges can be positive or negative, but for gravitational force the planets are considered and the mass of the planets cannot be negative and therefore the gravitational force cannot be repulsive in nature.
Why can the electric force be 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.
What is attractive and repulsive forces in physics?
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. … Repulsive forces occur only when atoms are very close to each other.
Is electrostatic a conservative force?
The electrostatic or Coulomb force is conservative, which means that the work done on q is independent of the path taken, as we will demonstrate later. This is exactly analogous to the gravitational force. When a force is conservative, it is possible to define a potential energy associated with the force.
How do you find the repulsive force?
In the equation Felect = k • Q1 • Q2 / d2 , the symbol Felect represents the electrostatic force of attraction or repulsion between objects 1 and 2.
