Question

The magnitude of charge on an electron in coulombs is :

• A. $1.76\times {10}^{11}$
• B. $1.6\times {10}^{-19}$
• C. $9.1\times {10}^{-31}$
• D. $\text{None of these}$

Answer 1

The correct option is B $1.6\times {10}^{-19}$

The charge of the electron is equivalent to the magnitude of the elementry charge ( e ) but bearing a negative sign.Since the value of elementry charge ( e) is roughly $=1.6\times {10}^{-19}$ Hence charge of electron is $=-1.6\times {10}^{-19}$ so from here we can see the Magnitude of electronic charge is $|e|=1.6\times {10}^{-19}$ C
