Question

1. calculate what is the difference expressed in kilograms between the mass of a proton and the mass of an electron?

Explanation:

Step1: Recall the masses

The mass of a proton \(m_p = 1.6726\times10^{-27}\space kg\), and the mass of an electron \(m_e=9.1094\times 10^{-31}\space kg\)

Step2: Calculate the difference

\(\Delta m=m_p - m_e=(1.6726\times10^{-27})-(9.1094\times 10^{-31})\)
