WebJun 16, 2024 · Quantisation of Charge Charge exists in discrete amount rather than continuous value and hence, quantised. Mathematically, charge on an object, q=±ne where, n is an integer and e is electronic charge. When any physical quantity exists in discrete packets rather than in continuous amount, the quantity is said to be quantised.

WebMay 22, 2024 · There are two types of charges : Positive charge Negative charge Positive and negative charges : Positive charge means the deficiency of electrons while negative charge means excess of electrons. In any neutral body the net charge is equal to zero i.e., the sum of positive charges is equal to the sum of negative charges. WebApr 4, 2024 · The Electric field formula is. E = F/q. Where E is the electric field. F (force acting on the charge) q is the charge surrounded by its electric field. If two charges, Q and q, are separated from each other by a distance r, then the electrical force can be defined as. F= k Qq/r2.
