# Problem: How will the desired centripetal force be set?1. By measuring the velocity, radius, and mass of the test mass.2. By choosing a value for the hanging mass.3. By measuring the acceleration and mass of the test mass.4. The centripetal force will not be set in this experiment.

###### FREE Expert Solution

Centripetal force:

$\overline{){{\mathbf{F}}}_{{\mathbf{C}}}{\mathbf{=}}\frac{\mathbf{m}{\mathbf{v}}^{\mathbf{2}}}{\mathbf{r}}}$

Centripetal force is due to tension on the hanging mass.

###### Problem Details

How will the desired centripetal force be set?

1. By measuring the velocity, radius, and mass of the test mass.

2. By choosing a value for the hanging mass.

3. By measuring the acceleration and mass of the test mass.

4. The centripetal force will not be set in this experiment.
