Quick Answer: Can both the electrostatic force and the gravitational force be either attractive or repulsive?

Can both electric and gravitational forces be attractive and repulsive?

It may seem that the two forces are related but that is not the case. … Another major difference between the two forces is that gravitational force can only be attractive, whereas electrostatic could be attractive or repulsive, depending on the sign of charges; unlike charges attract and like charges repel.

Can electrostatic force be attractive or repulsive?

Electric field

If two charges have the same sign, the electrostatic force between them is repulsive; if they have different sign, the force between them is attractive.

Can gravitational force be repulsive like electrostatic force?

Gravitational forces can also be repulsive like that of electrostatic forces. … Electrostatic force is defined as an attractive or repulsive force between the two electrically charged objects; it is also known as the Coulomb force.

Which forces can either be attractive or repulsive?

Electromagnetic forces can be either attractive or repulsive. They are long-range forces, which act over extremely large distances, and they nearly cancel for macroscopic objects. (Remember that it is the net external force that is important.)

How are electrostatic and gravitational force similar?

They both act between two bodies without any means of contact. However gravitational force acts on mass while the electric force acts on charge. Gravitational force are only attractive while electric field can be attractive/repulsive.

What are the similarities between gravitational force and electrostatic force?

Both act in a vacuum. Both are central and conservative. Both obey an inverse-square law .

Which force is both attractive and repulsive in nature?

Electromagnetism is both an attractive and repulsive force between particles with a property called charge, which come in two varieties – positive and negative.

Is gravitational force attractive?

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.

What determines whether the electrostatic force between two charged particles is attractive or repulsive?

In Coulomb’s law, however, the magnitude and sign of the electric force are determined by the electric charge, rather than the mass, of an object. … 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 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.

Is gravitational force is always attractive repulsive?

Complete answer: We know that the gravitational force is defined as the multiplication of the gravitational constant along with the masses of the objects and then divided by the square of the distance between the objects. … Hence, the nature of the gravitational force will always be attractive and not repulsive.

Can positive force be both attractive and repulsive?

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. …

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.
