Answer 1

`\stackrel{ electron }{9.1* 10^(-31)}\hspace{5em}\stackrel{\textit{\small proton} }{\stackrel{ \textit{1900 times more}}{1900* (9.1* 10^(-31))}} \\\\[-0.35em] ~\dotfill\\\\ 1900* (9.1* 10^(-31))\implies (1.900* 10^(3)) (9.1* 10^(-31)) \\\\\\ (1.9* 10^(3)) (9.1* 10^(-31))\implies (1.9* 9.1)(10^3* 10^(-31))\implies (17.29)(10^(3-31)) \\\\\\ 17.29* 10^(-28)\implies {\Large \begin{array}{llll} 1.729* 10^(-27) \end{array}}`
