Question

difference between physical force and electrical force

Answer 1

Electrostatic force is force between two charges separated by distance in space while gravitational force is the force between two masses separated by a distance.Electrostatic force is either repulsive or attractive while gravitational force is always attractive.Two charges 1 coulomb each separated by a distance 1 meter in space is will attract or repulse with a force of 9×109N while two masses each of 1kg separated by a distance 1m will attracted by a force of 6.67×10-11N. That is gravitational force is much weaker than electrostatic force.Electrostatic arises due to influence of electric field on a charge mediated by photons while gravitational force arises due to curvature of space by the presence of mass.  

Answer 2

Answer:

Electric force exists between charges, as described by Coulomb's Law. ... Electrostatic force is described by Coulomb's Law. We use Coulomb's Law to solve the forces created by configurations of charge. Electrostatics deals with forces between charges.
