Electric field: Space around a charge in which its influence can be felt by any other charged particle. This means that the Coulombs force exerted on q2 by q1 is equal and opposite to the Coulombs force exerted on q1 by q2; in accordance with Newtons third law.Thus, Newtons third law also holds good for electrical forces. It is the basic property associated with matter due to which it produces and experiences electric and magnetic effect. To determine the direction of an electric field, consider a point charge q as a source charge. The electric field at point P due to q is (As q 0 tends to zero the electric field produced by q is not affected by q 0.) The proportionality constant k in Coulombs law is similar to G in Newtons law of gravitation. where E is the electric field's strength, F is the electric force, q is the test charge. It is denoted by symbol 'q'. is approximately, The constant k is often written in terms of another constant, 0, called the permittivity of free space. The amount of force experienced by a unit charge placed at that point in a electric field.
