Total charge transferred from one body to other can be calculated by the number of electrons it is known as quantisation of charge given by q=?ne, where n= number of electrons , which should be an integer.
7) Charge is quantized means
charges can take on discrete values that are multiples of charge on electron
Related Electricity MCQ with Answers
gain or loss of one or more electrons
It is not possible to remove or add protons to atom, but electron can be added or removed by an atom easily so charge can be developed on an atom removing or adding electrons , by adding becomes negative ,by removing becomes positive.
force exerted by one charge on another when the two are at rest in a given frame of reference
Electrostatics means charges at rest ,or relatively at rest so this force can be applicable only when charge produce electric field which is constant which is possible only when charges at rest or relatively at rest.
that allow movement of electrons
In conductors some electrons are unpaired so these electrons can move freely.
a metallic object is charged by bringing a charged object near it
If a charged object placed near an uncharge object than redistribution of charge takes place in uncharge object and if we will earthed one surface of uncharged object than one charge goes to earth and other charge spread on its surface and it becomes charged.
