Question

Give the properties of Coulomb’s force.​

Answer 1

Explanation:

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.

The size of the force varies inversely as the square of the distance between the two charges. Therefore, if the distance between the two charges is doubled, the attraction or repulsion becomes weaker, decreasing to one-fourth of the original value. If the charges come 10 times closer, the size of the force increases by a factor of 100.

The size of the force is proportional to the value of each charge. The unit used to measure charge is the coulomb (C). If there were two positive charges, one of 0.1 coulomb and the second of 0.2 coulomb, they would repel each other with a force that depends on the product 0.2 × 0.1. Thus, if each of the charges were reduced by one-half, the repulsion would be reduced to one-quarter of its former value.

Answer 2

Required Answer:-

Properties of Coulomb's force:

• Coulomb force is the attraction or repulsion of particles because of their electric charge.
• Coulomb force obeys the inverse square law.
• It follows the superposition principle.
• It is dependent from medium, the magnitude of force is affected when the vaccum is replaced by another medium.

Know More:-

• Coulomb force is the electric force between charged bodies at rest.
• Coulomb force is also known as electrostatic force.

★ Formula: $\bf F = k \dfrac{q_1q_2}{r^2}$

• F = Electric force
• k = Coulomb constant
• $\sf q_1 , \ q_2$ are the charges
• r = distance of seperation
