27 Charges can neither be created nor destroyed it can be transferred from one place to another The force between two charges are given by coulomb s law To find the force acting on a unit positive test charge electric field is calculated due to that charge The electric field always originates from ve charge and ends on ve charge Electromagnetic waves can be generated that transported energy i Does Coulomb s law agree with Newton s 3rd law a No b Yes c May be d Can t say ii What is the inherent characteristic of matter a Charge is inherent characteristic b Quantization of charges c Coulomb s law is not applicable in vacuum d None of the above iii Are electric field E and force F vector or scalar quantity a E is vector quantity and F is scalar b E and F are vector quantity c E is scalar F is vector d E and F is scalar iv Can Coulomb s law be used to define unit of charge a Yes b No c May be d Can t comment v Is physical significance of EM field useful in electrostatics a Yes b No c May be 5
