On the other hand, one may show that the gravitational force is only. The electrostatic force between the two particles is approximately. Cbse ncert notes class 12 physics electric charges fields. It is the net charge enclosed in the surface that matters in gausss law but the total flux of electric field e depends also on the surface chosen not merely on the charge enclosed. The electric field at the point q due to q is simply the force per unit positive charge at the point q. Is directly proportional to product of magnitude of the two charges. Electrostatic phenomena arise from the forces that electric charges exert on each other and are described by coulombs law. Electrostatics class 12 and iitjee summary pdf download. E must be normal tothis surface and must have same magnitude for all pointson the surface. The electric field is a physical object which can carry both momentum and energy. Is inversely proportional to square of the distance between these charges and. In physics, electrostatics deals with the phenomena and properties of stationary or slowmoving electric charges.
