Question 4

If a body moving in a circular path maintains constant speed of 10 m s$$^{-1}$$, then which of the following correctly describes the relation between acceleration and radius?

The formula for centripetal acceleration is $$a = \frac{v^2}{r}$$

Since $$v^2$$ is constant, the relationship becomes $$a \propto \frac{1}{r}$$

This represents a rectangular hyperbola.

Option (D) represents this correctly.
