Question

Calculate the total mass of electron having total charge of 1 coulomb

Answer 1

Answer:

5.69×10^-12kg

Explanation:

wkt, Q=±ne (Quantization of electric charge)

Here, Q=1C

and e=1.6×10^-19 C

i.e, n=Q/e = 1÷1.6×10^-19= 6.25×10^18.

Now, mass of 1 electron = 9.1×10^-31 kg

i.e, total mass = (6.25×10^18) × 9.1×10^-31 =56.875×10^-13 =5.69×10^-12kg.
