If your body develops a charge of -19 μc (microcoulombs), how many excess electrons has it acquired?

Answer : The number of electrons it acquired is, electrons

Solution : Given,

Total charge =        

Charge on one electron =

Formula used :

Now put all the given values in this formula, we get the number of electrons.

Therefore, the number of electrons it acquired is, electrons.
