When \(10^{19}\) electrons are removed from a neutral metal plate through some process, the charge on it becomes __________.
- A -1.6 C
- B +1.6 C
- C \(10^{19} C\)
- D \(10^{-19} C\)
Answer & Solution
Correct Answer
(B) +1.6 C
Step-by-step Solution
Detailed explanation
(B)
\(\begin{aligned} Q & =n e \\ & =10^{19} \times 1.6 \times 10^{-19} \\ & =1.6 C \end{aligned}\)
Removal of electrons opens up a positive charge.
\(\begin{aligned} Q & =n e \\ & =10^{19} \times 1.6 \times 10^{-19} \\ & =1.6 C \end{aligned}\)
Removal of electrons opens up a positive charge.
