Acceleration 61824

On a sphere weighing 100 g, which lies on a horizontal plate, a force acts in the horizontal direction, which gives it an acceleration of 20 cm. s ^ -2. Find the magnitude of the force.

Correct answer:

F =  0.02 N

Step-by-step explanation:

$$\begin{gathered} m=100\text{g}\to \text{kg}=100:1000\text{kg}=0.1\text{kg} \\ a=20/100=\frac{1}{5}=0.2{\text{m/s}}^2 \\ F=m\cdot a=0.1\cdot 0.2=0.02\text{N} \end{gathered}$$
