Question

According to Coulomb’s law, the force between two charges acts along the straight line joining the charges. The force is directly proportional to the product of the charges, and inversely proportional to the square of the distances between the charges. This law is similar to
A) the kinetic theory of gases.
B) Newton’s third law of motion.
C) the first law of thermodynamics.
D) the universal law of gravitation.

Answer 1

Answer:

D) the universal law of gravitation.

Explanation:

Based on the statement of the Coulomb's law, it is easy to conclude that the law is similar to the universal law of gravitation.

Newton's law of universal gravitation is one of the most interesting physical laws out there.

It states that "the gravitational force of attraction between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distances between the charges".

Recalling the coulomb's law, we can clearly see that both shows a direct proportionality of force to quantity of charges/mass and inverse proportionality to the square of the distances between them.
