1. Definition   Electric field is the area around the electric charge where the charged particles in it experience electrostatic force. 2. Formula  3. Important Figure  James Clerk Maxwell was a Scottish physicist who examined Faraday's ideas concerning the link between electricity and magnetism interpreted in terms of fields of force, Faraday had shown that when a wire moves within the field of a magnet, it causes an electric current to flow along the wire. Maxwell took Faraday's experimental discoveries in the field of electromagnetism and provided a mathematical explanation, which outlined the relationship between magnetic and electric fields. He published his 'Dynamical Theory of the Magnetic Field' in 1864 and in 1873 he published 'Treatise on Electricity and Magnetism' . 4. Uses in Everyday Life   Faraday cages are built by taking a conducting material and forming an enclosure, as shown in the picture above, the pers...

  1. Definition  Electric force is the attractive force or the repulsion force between two charges of the same or opposite type where the force is directly proportional to the sum of the two charges and inversely proportional to the square of the distance. 2. Formula and Example Where: F is the electric force (N) q1 and q2 are the signed magnitudes of the charges (C) r is the distance between the charges (m) k is the Coulomb's constant 9 × 10 9  Nm 2 ·C −2 Example:  A positive charge q exerts a force of magnitude -0.20 N on another charge -2q. Find the magnitude of each charge if the distance separating them is equal to 50  cm. Solution: F = k (q) ( - 2q) / r 2 , r = 0.5 m , F = - 0.20 N , - 0.2 = - 2 q 2 k / 0.5 2 q 2 = 0.2 × 0.5 2 / (2 k) q = √ [ (0.2 × 0.5 2 / (2 × 9 × 10 9 ) ] = 1.66 × 10 -6 C q = 1.66 × 10 -6 C , -2 q = -3.23 × 10 -6 C  3.
