Question

calculate the number of electrons constituting 16 coloumbs of charge?​

Answer 1

Step-by-step explanation:

We Have :-

16 C Charge

To Find :-

Number of electrons constituting 16 coloumbs of charge

Solution :-

$we \: know \: that \: \\ \\ \\ charge \: on \: 1 \: electron \: = 1.6 \times 10 ^{ - 19} c \\ \\ \\ 1 \: c \: charge = \dfrac{1}{1.6 \times 10^{ - 19} } \\ \\ \\ = 6.25 \times 10^{18} \: electrons \\ \\ \\ 16 \: c \: charge \: = 6.25 \times 10^{18} \times 16 \\ \\ \\ = 1 \times 10 ^{20} electrons$

❏ Question:-

@ Calculate the number of electrons constituting 16 coloumbs of charge?

❏ Solution:-

Now , we know that

$\longrightarrow 1\:e^-=1.6\times10^{-19}\:C$

$\longrightarrow\dfrac{ 1}{1.6\times10^{-19}}\:e^-=1\:C$

$\longrightarrow 1\:C=\dfrac{ 1}{1.6\times10^{-19}}\:e^-$

$\therefore\:\:\: 16\:C=\dfrac{ 1}{1.6\times10^{-19}}\times16\:e^-$

$\longrightarrow \large{\boxed{16\:C=1\times10^{20}\:e^-}}$

∴ 16 Coulomb Charge Contain $10^{20}$ electrons .
