Question

4.9 q: what is the weight of a 2.00 - kilogram object on the surface of earth? (a) 4.91 n (b) 2.00 n (c) 9.81 n (d) 19.6 n

Explanation:

Step1: Recall the formula for weight

Weight \(W = mg\), where \(m\) is mass and \(g\) is acceleration due to gravity (\(g = 9.8\ m/s^{2}\) on Earth's surface).

Step2: Substitute the given values

Given \(m = 2.00\ kg\) and \(g=9.8\ m/s^{2}\), then \(W=(2.00\ kg)\times(9.8\ m/s^{2})\).

Step3: Calculate the weight

\(W = 19.6\ N\)

Answer:

D. 19.6 N
