Question

The charge of an object is -
-4.8 micro coulomb.Calculate the
number of electrons it has gained.​

Answer 1

Answer:

charge on object = -4.8×10^-6C

charge on 1 electron= -1.6×10^-19C

No. of electrons= charge on object / charge of electron

= -4.8×10^-6 / -1.6×10^-19

= 3×10^13 electrons
