What is the similarities of coulomb's law to gravitational force?

Answer 1

Coulombs law is similar to Newtons law of Gravitation in that each force has an inverse square relation with the distance between the two bodies interacting. Coulombs law can be applied to the repulsive force of like charges as well, where as gravity is only an attractive force.

Answer 2

Pretty much everything. Newton's Law deals with gravity and mass, Coulomb's Law involves electrical charge and electrical current.

its value n its constant is also different newtons law have gravitational constant G n columbs law have columb's constant both of them have different values

Answer2:

Newton and Coulomb's Law differ in the constant, Newton's constant is gravity G and Coulomb's law is Planck's Constant.

Newton's law is F = -mGM/r = -vh/2pir^2 = -vp/r where v= (GM/r)^.5 and h= 2pi (GMr)^.5

Coulomb,s law is F = -e^2 zc/4pir^2 = -vh/2pir^2 = -vp/r where h is Planck,s Constant and v= c alpha

Answer 3

The mathematical expression for the force between charges is identical to the expression for the gravitational force between masses. The force between two (charges/masses) is proportional to the product of the (charges/masses) and inversely proportional to the square of the distance between their centers. The differences between the two cases are: -- There are two kinds of charge, which can produce either attractive or repulsive force. But there is only one kind of mass, and the force of gravity is always attractive. -- The constant of proportionality for charges is something like 1040 greater than the gravitational constant.

Answer 4

Both Coulomb's law and gravitational force follow an inverse square law, where the force decreases with the square of the distance between the two particles. Both forces are vector quantities, meaning they have both magnitude and direction. Additionally, both forces are fundamental forces of nature that govern the interactions between particles.

Answer 5

Both show force is inversely proportional to the square of distance and directly proportional to the product of 2 masses, for gravity or 2 charges. for Coulombs law.

Answer 6

The main similarity is the inverse-square relationship.

Answer 7

Both involve an inverse square law.
