Question

Which is equivalent to three (3) elementary charges?(a) 1.6 x 10-19 C (b) 2.0 x 10-19 C (c) 4.8 x 10-19 C (d) 5.4 x 10-19 C

Answer 1

The value of the elementary charge is

`e=1.6*10^(-19)\text{ C}`

We have to find a charge equivalent to 3e.

The charge equivalent to 3e will be

`\begin{gathered} 3e\text{ = 3}*1.6*10^(-19)\text{ C} \\ =4.8*10^(-19)\text{ C} \end{gathered}`

Thus, the correct option is c.
