Answer 2

${\large{\bold{\sf{\underline{LET'S \; UNDERSTAND \; THE \; QUESTION \; FIRST :-}}}}}$

the mass of a proton is $\tt 1.67262 × 10 ^{ - 27}$ kg and the mass of electron is $\tt9.10938 × {10}^{ - 13}$ kg . show that the mass of proton is nearly 2,000 times the mass of an electron

Let's solve it !!

$\rule{150}{2}$

${\large{\bold{\sf{\underline{FULL \; SOLUTION :-}}}}}$

${\bold{\sf{:\implies \dfrac{mass \: of \: proton}{mass \: of \: electron} \: = \: \dfrac{1.67262 \times {10}^{ - 27} }{9.10938 \times {10}^{ - 31} } }}}$

⠀

${\bold{\sf{:\implies \dfrac{mass \: of \: proton}{mass \: of \: electron} \: = \: \dfrac{1.67262 }{9.10938 } \times {10}^{ - 27 - ( - 31)} }}}$

⠀

${\bold{\sf{:\implies \dfrac{mass \: of \: proton}{mass \: of \: electron} \: = \: \dfrac{1.67262 }{9.10938 } \times {10}^{ - 27 + 31} }}}$

⠀

${\bold{\sf{:\implies \dfrac{mass \: of \: proton}{mass \: of \: electron} \: = \: \dfrac{1.67262 }{9.10938 } \times {10}^{ 4} }}}$

⠀

${\bold{\sf{:\implies \dfrac{mass \: of \: proton}{mass \: of \: electron} \: = \: 0.1836151 \times 10 ^{4}≈2000(approx.) }}}$
