Question

The magnitude of the charge on an electron is:

विकल्प

• \(e = 6.25 \times 10^{-18}\ \text{C}\)

• \(e = 9.1 \times 10^{-31}\ \text{C}\)

• \(e = 1.6 \times 10^{19}\ \text{C}\)

• \(e = 1.6 \times 10^{-19}\ \text{C}\)

Answer 1

The charge of an electron is \(e = 1.6 \times 10^{-19}\ \text{C}\) (negative in sign). Note that \(9.1 \times 10^{-31}\ \text{kg}\) is the electron's mass, not its charge.
