When \(10^{19}\) electrons are removed from a neutral metal plate, the electric charge on it is
- A \(-1.6 \mathrm{C}\)
- B \(+1.6 \mathrm{C}\)
- C \(10^{+19} \mathrm{C}\)
- D \(10^{-19} \mathrm{C}\)
Answer & Solution
Correct Answer
(B) \(+1.6 \mathrm{C}\)
Step-by-step Solution
Detailed explanation
Charge, \(q=n e\) \(\Rightarrow \quad q=10^{19} \times 1.6 \times 10^{-19}=1.6 \mathrm{C}\)
