Centripetal acceleration in a circular path:

$\overline{){\mathbf{\alpha}}{\mathbf{=}}\frac{{\mathbf{v}}^{\mathbf{2}}}{\mathbf{r}}}$

The acceleration is inversely proportional to the radius.

If an object travels at a constant speed in a circular path, the acceleration of the object is:

1- larger in magnitude the smaller the radius of the circle.

2- smaller in magnitude the smaller the radius of the circle.

3- in the same direction as the velocity of the object.

4- in the opposite direction of the velocity of the object.

5- zero.
