Understanding the Balance
In a simple balance, both sides must have equal weight to remain balanced. When comparing weights, it’s essential to convert all units to the same measurement system, either grams or kilograms.
Weight Conversions
- 1 kg = 1000 g
- Therefore:
- 4 kg = 4000 g
- 400 g = 0.4 kg
- 500 g = 0.5 kg
- Half kg = 0.5 kg
- 3 kg = 3000 g
- 300 g = 0.3 kg
Analyzing Each Option
- Option A: 40 g and 4 kg
- 40 g vs. 4000 g (not balanced)
- Option B: 4 kg and 400 g
- 4000 g vs. 400 g (not balanced)
- Option C: 500 g and half kg
- 500 g vs. 500 g (balanced)
- Option D: 3 kg and 300 g
- 3000 g vs. 300 g (not balanced)
Conclusion
The only combination that keeps both sides of the balance equal is Option C: 500 g and half kg. Both weights are equivalent to 500 g, ensuring that the balance remains stable.
This balance principle is fundamental in physics and everyday life, teaching the importance of equal weights in achieving equilibrium.
