Using Newton's Second Law, what is the weight force of a 2.00 kg object on Earth?

To determine the weight force of an object, we can use Newton's Second Law, which states that force is equal to mass times acceleration (F = m * a). In the case of weight, the acceleration in question is due to gravity. On Earth, the acceleration due to gravity is approximately 9.8 m/s².

In this situation, we have a 2.00 kg object. To find its weight force, we multiply the mass of the object by the acceleration due to gravity:

Weight force (W) = mass (m) × gravitational acceleration (g)
W = 2.00 kg × 9.8 m/s²
W = 19.6 kg·m/s², which can also be expressed as 19.6 N (Newtons).

Thus, the weight force of a 2.00 kg object on Earth is 19.6 kg·m/s². This value represents the force with which the Earth pulls the object towards itself, indicating its weight.

The other values presented do not correctly apply the formula or consider the gravitational acceleration appropriately for the given mass, leading to incorrect estimates of the object's weight.
