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
(A) \(+1.6 \mathrm{~C}\)
Step-by-step Solution
Detailed explanation
The charge \(q\) on a body is given by the quantization formula \(q = ne\), where \(n\) is the number of electrons removed or added and \(e\) is the elementary charge. Given \(n = 10^{19}\) and \(e = 1.6 \times 10^{-19} \text{ C}\). Since electrons are removed from the neutral…
