Both have the concept of variation of force inversely with the square of the distance.
But in case of coulomb we have electric charges and in case of newton's gravitation law we have masses. Coulomb's force can be either attractive and repulsive where as Newton's is only attractive
Coloumb's law is applicable for ionic species, but Newtons law is applicable for any mass body of this universe. On the other hand Newton's force is attractive force always but Coloumbic force is attractive and repulsive also.
The main similarity is that both are inverse square laws.The differences are that gravity is always attractive; the electrostatic force can be attractive or repulsive; also, gravity depends on mass (and affects all objects), whereas the electrostatic force affects electric charges.
Newtons law has to due with mass and ATTRACTION only
Coulombs law has to due with charge and ATTRACTION AND REPULSION
One difference is that electrical attraction can be both attractive and repulsive.
Both are 'Inverse square' forces, f=k/r2 .
newtons gravitational law is similar to that of coulomb's law...
Coulombs law is given by the equation:F=kq1*q2/r^2 This means that the force of attration between two particles is = to k(9.11810^9) times the product of their charges divided by the distance apart sqaured. The final units are in Newtons. And in this equation k is a constant given by: 9E9 N*m^2/C^2
Q refers to charges. Charges are measured in coulombs.
Coulumbs law is applicable only for static fields that is when charges are stationary
Newtons law has to due with mass and ATTRACTION only Coulombs law has to due with charge and ATTRACTION AND REPULSION
Both are 'Inverse square' forces, f=k/r2 .
newtons gravitational law is similar to that of coulomb's law...
newtons * meters squared / coulombs squared

coulombs law
yes they r same
The force between two charges (masses) is proportional to the product of the charges (masses) and inversely proportional (same) to the distance between them. The formula for the force between two charges (masses) has the same exact form in both cases.
