Question

Determine the total charge on 18.2 kg of electrons?​

Answer 1

$\huge{ \bold{ \red{ \underline{Answer:-}}}}$

$\bold{charge \: on \: one \: electron \: =1.602 \times 10 {}^{ - 19} \: C } \\ \bold{mass \: on \: one \: electron \: = \: 9.11 \times 10 {}^{ - 13} kg} \\ \bold{given \: mass \: = 18.2 \: kg}$

$\bold{∴ \: Total \: charge \: = \frac{18.2 \times 1.602 \times 10 {}^{ - 19} }{9.11 \times 10 {}^{ - 31} } } \\ \bold{ = > \frac{29.16 \times 10 {}^{12} }{9.11} } \\ \boxed{\bold{= > 3.2 \times 10 {}^{12} \: C}}$
