Question

Which of the following is true about the charge of an electron?

a. It is 1.602 x 10^-19 C, and the smallest unit of charge
b. It is -1.602 x 10^-19 C, and the smallest unit of charge (THIS ANSWER IS CORRECT)
c. It is -1.602 x 10^-19, and it is a multiple of the smallest unit of charge
d. It is 1.602 x 10^-19, and it is a multiple of the smallest unit of charge

Answer 1

It is -1.602 x 10^-19 C, and the smallest unit of charge

Explanation:

The charge on an electron is
`1.6* 10^(-19)\ C`. The charge on electron is negative. The quantization of electric charge is :

q = ne

q is net charge

n is no of electrons

e is the electronic charge which is
`-1.6* 10^(-19)\ C`. Hence, the correct option is (b).
