- 9.8 kW
- 980 kW
- 98 kW
- 10 kW
- 100 kW
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Concept
Power is the product of force and velocity ($P = F \cdot v$).
Step 2: Meaning
Force $F = 500 \text{ N}$ and velocity $v = 20~ms^{-1}$.
Step 3: Analysis
$P = 500 \times 20 = 10,000 \text{ Watts}$.
Step 4: Conclusion
$10,000 \text{ W} = 10 \text{ kW}$. Final Answer: (D)
