Question

you have a iron sphere of 280 miligram if 0.01% of total electron in it are removed then find :- (1) change in mass and charge​

Answer 1

The atoic weight of iron is

Thus, <br> 56 g of iron contains

atoms and each atom contains 26 electrons. Hence, 280 mg of iron contains <br>

electron <br> . The number of electrons transferred from one particle <br> to another <br>

The charge transferred is, therefore, <br>

<br> The electric force between the particles is <br>

<br>

N <br> . This equals the load of apporximately 2000 million <br> grown- up persons!
