Question

find out the no of electrons in a charge of -1c​

Answer 1

Answer:

-1.602 x 10^-19 C

Explanation:

Since the value of the elementary charge is roughly 1.602 x 10^-19C, then the charge of the electron is -1.602 x 10^-19 C.

Answer 2

Answer:

6.25x10^18 electrons

Explanation:

q=ne (according to quantisation of charge)

-1=n*-1.6*10^-19

1/1.6*10^-19=n

1x10^19/1.6=n

0.625 *10^19=n

n=6.25*10^18 electrons
