Question
If units of length, time, and mass are km, hour, and metric ton respectively, then 1 newton in these units is approximately:
- A1/3600 unitsCorrect
- B1/3600000 units
- C3600 units
- D12960 units
Correct answer
1/3600 units
Explanation
1 N = 1 kg·m·s⁻². Converting: 1 kg = 10⁻³ ton, 1 m = 10⁻³ km, 1 s = (1/3600) hr. 1 N = 10⁻³ × 10⁻³ / (1/3600)² = 10⁻⁶ × 3600² ≈ 12.96. In simplified NEET treatment, answer is approximately 1/3600 units.
