  • A Kgms-2
  • B Kgm2s-3
  • C Kgm2s-2
  • D Kgm2s-1
Correct Answer: Option B
Explanation:
\(Power = \frac{\text{Work done}}{time}\)
= \(\frac{Force \times distance}{time}\)
= \(\frac{mass \times acceleration \times distance}{time}\)
= \(\frac{kg \times m \times m}{s^{2} \times s}\)
= \(kgm^{2} s^{-3}\)
