Question

The elementary of a proton is 1.6x 10 to the negative 19th C. Using this information, calculate the charge on 2 x 10 to the 14th protons.

Answer 1

QUESTION

The charge of a proton is $q_p = 1.6 \cdot 10^{-19} \, C$. Using this information, calculate the charge on $N = 2.4 \cdot 10^{14}$ protons.

SOLUTION:

The charge of $2 \cdot 10^{14}$ protons is

$$Q = N \cdot q_p = 2 \cdot 10^{14} \cdot 1.6 \cdot 10^{-19} \, C = 3.2 \cdot 10^{-5} \, C = 32 \cdot 10^{-6} \, C = 32 \, \mu C$$

ANSWER

$32 \, \mu C$
