Question

How much electric charge is present on 100 protons?
(a) 6*10^-19 C
(b) 6*10^-17 C
(c) 1.6*10^-19 C
(d) 1.6*10^-17 C​

Answer 1

$\blue{\bold{\underline{\underline{Answer:}}}}$

$\green{\tt{\therefore{Electric\:charge=1.6\times 10^{-17}\:C}}}$

$\orange{\bold{\underline{\underline{Step-by-step\:explanation:}}}}$

$\green{\underline \bold{Given :}} \\ \tt: \implies Number \: of \: protons(n) = 100 \\ \\ \red{\underline \bold{To \: Find :}} \\ \tt: \implies Electric \: charge(Q) =?$

• According to given question :

$\tt \circ \: e = 1.6 \times {10}^{ - 19} \: C \\ \\ \bold{As \: we \: know \: that} \\ \tt: \implies Q= ne \\ \\ \tt: \implies Q = 100 \times 1.6 \times {10}^{ - 19} \\ \\ \tt: \implies Q = 1.6 \times {10}^{2} \times {10}^{ - 19} \\ \\ \tt: \implies Q = 1.6 \times {10}^{ - 19 + 2} \\ \\ \green{\tt: \implies Q = 1.6 \times {10}^{ - 17} \: C}$
