A bicycle generator crcates \(1.5 \mathrm{~V}\) at \(15 \mathrm{~km} / \mathrm{h}\). The cmf generated at \(10 \mathrm{~km} / \mathrm{h}\) is
- A \(1.5 \mathrm{~V}\)
- B \(2 \mathrm{~V}\)
- C \(0.5 \mathrm{~V}\)
- D \(1 \mathrm{~V}\)
Answer & Solution
Correct Answer
(D) \(1 \mathrm{~V}\)
Step-by-step Solution
Detailed explanation
Initial speed of bicycle, \(v_{1}=15 \mathrm{~km} / \mathrm{h}\) Emf produced, \(e_{1}=15 \mathrm{~V}\) Final speed of bicycle, \(v_{2}=10 \mathrm{~km} / \mathrm{h}\) If emf generated at speed \(v_{2}\) be \(e_{2}\), then…
