Chapter 1: Problem 12

The approximate value of charge of an electron is ............. (a) \(10^{-18} \mathrm{c}\) (b) \(10^{+15} \mathrm{c}\) (c) \(10^{-38} \mathrm{c}\) (d) \(10^{-19} \mathrm{c}\)

Short Answer

Expert verified
The approximate value of the charge of an electron is given by option (d) \(10^{-19} \mathrm{C}\).

Step by step solution

01

Recall the elementary charge value

According to the International System of Units (SI), the elementary charge is a fundamental constant and its assigned symbol is \(e\). For an electron, its charge is negative and represented as \(-e\), while for a proton, it is positive and represented as \(+e\).
02

Find the elementary charge value

The elementary charge has a value of approximately \(1.6 \times 10^{-19} \mathrm{C}\) (\(\mathrm{C}\) denotes Coulomb, the unit used to measure electric charge). Since the charge of an electron is negative, its charge will be \(-1.6 \times 10^{-19} \mathrm{C}\).
03

Choose the correct option

Now, let's look at our options and see which one matches the value of the electron charge we found. Option (d) is \(-1 \times 10^{-19} \mathrm{C}\), which is the closest value to the charge of an electron.
04

Conclusion

Therefore, the approximate value of the charge of an electron is given by option (d) \(10^{-19} \mathrm{C}\). Note that the charge of an electron is negative, so the correct answer should actually be \(-1 \times 10^{-19}\mathrm{C}\), but we assume that the negative sign has been omitted in the question for simplicity.
