Question

explain the principprincipleof quantization of charges. Can a charge of 8*10^-18 C be given to a body ​

Answer 1

Answer:

First u must know the elementary charge i.e. is a charge carried by a single proton which is 1e or an electron which is -1e where e is elementary positive charge and not the electron. Elementary charge is a constant . Its value is nearly 1.6 × 10-¹⁹

Quantisation of charge is that charge of any object is only integer multiple of elementary charge i.e. it can be 1e, 2e, 3e,...... or -1e, -5e, -3e.....etc. but can't be a fraction or decimal ( some exceptions are there) . Take for example an object is there with n number of charges , elementary charge is e and let its quantisation of charge be Q so

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: Q = ne$

So this was the formula for quantisation of charge, say a thermocol ball have 13 positive charge then Q = 13 × e i.e. 13e . Take another example, say a cup with 1872829 negative charges so Q = 18722829 × e i.e. 18722829e.
