Why can we say that charge of any body is always an integral multiple of e ? |
|
Answer» Solution :If the protons and ELECTRONS are the only basic charges in the universe, all the observable charges have to be integral multiples of e. If a body containss `n_(1)`electrons and `n_2` protons, the total amount of CHARGE on the body is `n_(2)e + n_(1)(-e) = (n_(2) - n_(1))e` where `n_(1)`and `n_2` is integral multiples. and their DIFFERENCE = `n_(2)e - n_(1) (-e)` `=(n_(2) + n_(1))e` also an integer. Thus, the charge on any body is always an integral MULTIPLE of e and can be increased or decreased also in STEPS of e. |
