Question

Calculate the amount of charge represented by four million protons.

Answer 1

Given:

Number of protons = $4\;\times\;10^6$

To find:

The amount of charge represented by $4$ million protons

Points to know:

The charge of one proton = $+1.602\;\times\;10^{-19}$ C

Step-by-step explanation:

The charge on $4$ million protons = $4\;\times\;10^6\times\;1.602\;\times\;10^{-19}$ C

The charge on 4 million protons = $+6.408\;\times\;10^{-13}$ C

Answer:

The charge on 4 million protons = $+6.408\;\times\;10^{-13}$ C

Additional information:

• A proton is one of three main particles that constitute the atom.
• Protons are found in the nucleus of the atom.
• Protons have a positive electrical charge of $+1.602\;\times\;10^{-19}$ C, whereas the negatively charged electron has a charge of $-1.602\;\times\;10^{-19}$
