The potential difference between two parallel plates is \(10^4 \mathrm{~V}\). If the plates are separated by \(0.5 \mathrm{~cm}\), the force on an electron between the plates is
- A \(32 \times 10^{-13} \mathrm{~N}\)
- B \(0.32 \times 10^{-13} \mathrm{~N}\)
- C \(0.032 \times 10^{-13} \mathrm{~N}\)
- D \(3.2 \times 10^{-13} \mathrm{~N}\)
Answer & Solution
Correct Answer
(D) \(3.2 \times 10^{-13} \mathrm{~N}\)
Step-by-step Solution
Detailed explanation
The force \(F=\frac{e V}{d}\) \(=\frac{1.6 \times 10^{-19} \times 10^4}{0.5 \times 10^{-2}}\) \(=3.2 \times 10^{-13} \mathrm{~N}\)
