When a charge of \(3 \mathrm{C}\) is placed in uniform electric field, it experiences a force of \(3000 \mathrm{~N}\). Within this field, potential difference between two points separated by a distance of \(1 \mathrm{~cm}\) is
- A \(10 \mathrm{~V}\)
- B \(90 \mathrm{~V}\)
- C \(1000 \mathrm{~V}\)
- D \(3000 \mathrm{~V}\)
Answer & Solution
Correct Answer
(A) \(10 \mathrm{~V}\)
Step-by-step Solution
Detailed explanation
Electric force, \(F=q E\) and potential difference, \(\mathrm{V}=\mathrm{Ed}\)
\(\therefore \quad \mathrm{V}=\frac{\mathrm{Fd}}{\mathrm{q}}=\frac{3000 \times 10^{-2}}{3}=10 \mathrm{~V}\)
\(\therefore \quad \mathrm{V}=\frac{\mathrm{Fd}}{\mathrm{q}}=\frac{3000 \times 10^{-2}}{3}=10 \mathrm{~V}\)
