AP EAMCET · PHYSICS · Work Power Energy
An electric motor exerts a force of \(50 \mathrm{~N}\) on a a cable and pulls it through \(60 \mathrm{~m}\) in \(1 \mathrm{~min}\). The power supplied by the motor is
- A \(50 \mathrm{~W}\)
- B \(3000 \mathrm{~W}\)
- C \(1 \mathrm{~W}\)
- D \(100 \mathrm{~W}\)
Answer & Solution
Correct Answer
(A) \(50 \mathrm{~W}\)
Step-by-step Solution
Detailed explanation
Force exerted by electric motor, \[ F=50 \mathrm{~N} \] Displacement, \(s=60 \mathrm{~m}\) Time, \(t=1 \mathrm{~min}=60 \mathrm{~s}\) \(\therefore\) Power supplied by the motor,…
