A technician needs to measure the weight of a component near Earth's surface, where g=10 N kg−1g=10\ \text{N kg}^{-1}g=10 N kg−1. The component has a mass of 0.45 kg.
| newtonmeter | range | scale divisions |
|---|---|---|
| A | 0 to 5 N | 0.1 N |
| B | 0 to 20 N | 1 N |
Calculate the weight of the component and explain which newtonmeter the technician should use to measure it.
