To find the weight of an object, we can use the formula:
Weight (W) = mass (m) × gravitational acceleration (g)
In this case, we have a mass of 200 grams. First, we need to convert grams to kilograms because the standard unit of mass in the metric system is kilograms:
200 g = 0.2 kg
The standard gravitational acceleration on Earth is approximately 9.81 m/s².
Now, we can substitute the values into the formula:
W = 0.2 kg × 9.81 m/s² = 1.962 N
Therefore, the weight in newtons of an object with a mass of 200 grams is 1.962 N.
