DEPTH KWOWLEDGE IN ELECTROSTATICS

COLUMBUS LAW:

• Two charges express Columbus force due to interaction electric lines of force produce by charges.
• Magnitude of Coulomb;s force on the two charges will be always equal and opposite direction even charges and their masses may be or may not be equal and charges may be like or unlike.
• Force with negative sign represent attractive force and the convention is applied only in magnitude form.
• Above convention is applied only for Coulomb force, gravitational force and magnitude force between two current carrying wire.
• An electron is accelerating with potential of 1volt. Then find kinetic energy and speed gained by electron. Electron, proton,deuteron,Triton accelerating with potential of 1volt kinetic energy gained=1Ev=1.6^-19J.
• Insulator and conductor commonly called as dielectric is used as between charges to very Coulomb force and other electrostatics quantities.
• For pure water K=81(maximum) where K is relative permittivity or dielectric constant.
• For perfect insulator k=o i.e. perfect insulator cannot be charged by any method.
• Dielectric constant of medium epsilon cannot be equal to 1.
• Coulomb force will be maximum if between the charges is air or vacuum and after putting single dielectric completely between the charges then force, decrees by k time.
• If a conductor is kept completely or partially between the charges than Coulomb force decreases to zero.Since electric lines of force produced by charge cannot interact.
• Conductor constant is defined as property of medium which oppose electric lines of force.
• Conversation of charges is consequence of principle of continuity.
• Another left things i will write in another article.
