Angular frequency:

$\overline{){\mathbf{\omega}}{\mathbf{=}}\frac{\mathbf{v}}{\mathbf{r}}}$

Centripetal force:

$\overline{){{\mathbf{F}}}_{{\mathbf{C}}}{\mathbf{}}{\mathbf{=}}\frac{\mathbf{m}{\mathbf{v}}^{\mathbf{2}}}{\mathbf{r}}{\mathbf{\xb7}}\frac{\mathbf{r}}{\mathbf{r}}{\mathbf{=}}{\mathbf{m}}{\mathbf{r}}{{\mathbf{\omega}}}^{{\mathbf{2}}}}$

m and ω are the same for both.

The figure (figure 1) shows two balls of equal mass moving in vertical circles

Is the tension in string A greater than less than, or equal to the tension in string B if the balls travel over the top of the circle with equal angular velocity?

a. The tension in string A is greater than the tension in string B

b. The tension in string A is less than the tension in string B

c. The tension in string A is equal to the tension in string B
