The weight of an object of mass 1kg is approximately equal to ____ newton.
- A1
- B1000
- C10
- D100
Solution & Step-by-step Explanation
Weight (W) is given by the formula:
W=m×g
Where:
m=1kg (mass)
g≈9.8m/s
2
(acceleration due to gravity)
W=1×9.8=9.8N
Rounding 9.8N to the nearest integer gives 10 newtons.
