Question

Difference between gravitational and coulomb's law

Answer 1

Coulomb's law defines force between charges whereas Newton's law of gravitation defines force between masses. 2. Both are inverse square laws i.e. the forces are inversely proportional to the square of the distances between charges in case of Coulomb's law and between masses in case of Newton's law of gravitation.

Answer 2

Answer:

$\huge\mathfrak{coulomb's\:law}$

coulomb's law is states that ,the force of attraction or repulsion between two point charges is directly proportional to the product of charges ,and inversely proportional to the square of the distance between these charges,with a constant ,

F →q 1× q 2

F → 1/r^2

so ,F = k q 1 × q 2 / r ^2

where k is 1/4π e

here e is permittivity of free space or vacuum, value of k is 9× 10^9

$\huge\mathfrak{gravitational\:law}$

gravitational law states that ,,the force of attraction between two particles is directly proportional to the product of their masses,and inversely proportional to the square of the distance between them ,,

F → m1×m2

F → 1/r^2

now ,F = G m1×m2/r^2

here G is the gravitational Constant.
