Electric Charge and Electric Field MODULE - 5
Notes 1 Electric Charge and Electric FieldPHYSICSMODULE - 5 Electricity andMagnetism15 Electric Charge ANDELECTRIC FIELDSo far you have learnt about mechanical, thermal and optical systems and variousphenomena exhibited by them. The importance of electricity in our daily life istoo evident. The physical comforts we enjoy and the various devices used in dailylife depend on the availability of electrical energy. An electrical power failuredemonstrates directly our dependence on Electric and magnetic phenomena; thelights go off, the fans, coolers and air-conditioners in summer and heaters andgysers in winter stop working.
F = k 12 2 qq r × (15.1) For free space, we write F = 0 1 4πε × 12 2 qq r × (15.2) where constant of proportionality k = 0 1 4πε for free space (vacuum) and k = 1 4πε for a material medium. ε 0 is called permittivity of free space and ε is the permittivity of the medium. It means that if the same system of charges is kept in a material
