Question

3. How does the centripetal force change when

Answer 1

Answer:

The centripetal force increases.

Explanation:

Centripetal force is given by $F_c=ma_c$; where $a_c=\frac{v^2}{r}$.

Given these two equations, we can rewrite the formula for centripetal force as:

$F_c=m\frac{v^2}{r}$

As shown, radius is in the denominator, thus, a smaller radius would lead to a larger centripetal force.
