What is a main difference between the gravitational force and the electrostatic Coulomb force?

The basic difference between gravitational and electrostatic force is that:Gravitational force is the force by which earth attracts other objects by mass. It is a conservative force. While electrostatic force is the force of an object due to charge.

What is the difference between Coulomb’s law and Newton’s gravitational law?

Coulomb’s law explains the force between the charges whereas Newton’s law of gravitation explains the force between the masses. The electrostatic force may be positive or negative in the case of Coulomb’s law but the force is always negative in the case of Newton’s law of gravitation.

What are similarities between Newton’s law of gravitation and Coulomb’s law?

Similarities among the electrical and Gravitation force Both forces are conservative forces. Both forces obey the inverse square law. The charge ‘q’ plays the same role in the coulomb’s law that the mass ‘m’ plays in newton’s law of gravitation.

Why electrostatic force is called Coulomb’s force?

Coulomb force, also called electrostatic force or Coulomb interaction, attraction or repulsion of particles or objects because of their electric charge. Two like electric charges, both positive or both negative, repel each other along a straight line between their centres.

What are the similarities between Coulomb’s force and gravitational force?

Similarities between coulomb’s force and gravitational force Both Forces Coulomb’s and gravitational are directly proportional to the product of charges and masses of the body. Both Forces coulomb’s and gravitational are inversely proportional to the square of distance between them. Both forces are central forces.

What are the similarities between Coulomb force and gravitational force?

What are the similarities and dissimilarities between electrostatic force and gravitational force?

Electrostatic forces may be attractives or repulsive. But gravitational forces are always attractive. 3 Electrostatic forces between two protons is 1036 times stronger than gravitational forces between them.

What are some similarities between the electric force and the gravitational force What are some differences between the two forces Write your answer in a table?

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. Electric field is much stronger than gravitational field.

What is the difference between Coulomb’s law and Newton’s law of gravitation?

Similarly, in the case of Newton’s law of gravitation there is the same inverse proportionality between the force and the distance of masses. Both laws describe central forces, that is, forces that operate along the line connecting the two charges in the case of Coulomb’s law and the two masses in the case of Newton’s law of gravitation.

What are the similarities between Newton’s law of mass and electric force?

They are both inverse square laws. This means that the In case of electric forces they are inversely proportional to the square of the distances between charges. Similarly, in the case of Newton’s law of gravitation there is the same inverse proportionality between the force and the distance of masses.

What is the difference between electrostatic force and gravitational force?

Electrostatic force is either repulsive or attractive while gravitational force is always attractive. Two charges 1 coulomb each separated by a distance 1 meter in space is will attract or repulse with a force of 9×109N while two masses each of 1kg separated by a distance 1m will attracted by a force of 6.67×10-11N.

What is the value of G in Coulomb’s law?

The gravitational force between two masses is always attractive but Coulomb force between two charges can be attractive or repulsive, depending on the nature of charges. The value of the gravitational constant G = 6.626 x 10-11 N m2kg-2 . The value of the constant k in Coulomb law is k = 9 x 109 N m2 C2 .
