a ball has a mass of 2 kg. what is the balls weight on earth?\n2 n\n2 kg\n19.6 n\n0.20 n

Explanation:

Step1: Recall weight formula

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

Step2: Substitute values

Given $m = 2\ kg$ and $g=9.8\ m/s^{2}$, then $W=2\times9.8 = 19.6\ N$.

Answer:

C. 19.6 N
