Question

The order of magnitude of charge on electron 1.6 × 10-19 C is

(a) 10-18 C (b) 10-19 C (c) 1.6 × 10-20 C (d) 1.6 × 10-17 C

Answer 1

b) because the charge on an electron is 1.6 × 10-19 C

Answer 2

Answer:

The correct option is option b) $10^{-19}$

Explanation:

Here we have been given the magnitude of the charge of the negatively charged particle or the electron to be 1.6 × $10^{-19}$ C

We have been asked to find the order of the magnitude of this charged particle. Now since the charge given above is in its scientific notation we get the order to be $10^{-19}$ As we know that the order of the magnitude is the highest power of the 10 when the number is expressed in its scientific notation.

Hence the correct option among the four is option b) $10^{-19} C$
