  • When 10power 19 neutral particles are removed from a neutral plate then electric charge on it is

When 1019 electrons are removed from a neutral metal plate through some process, the charge on it becomes ____ ?

Answers (1)

\begin{aligned} &\text { Charge of one electron } \mathrm{e}=-1.6 \times 10^{-19} \mathrm{C}\\ &\text { So, total charge removed from neutral plate } \mathrm{Q}=\mathrm{ne}=10^{19} \times\left(-1.6 \times 10^{-19}\right)=-1.6 \mathrm{C} \end{aligned}

\begin{aligned} &\text { Earlier, charge on neutral plate was zero. since }-1.6 \mathrm{C} \text { charge is removed from it, so now it has }\\ &+1.6 \mathrm{C} \end{aligned}
