Explanation:
When an object moves in a circular path, centripetal force acts on it. The magnitude of centripetal acceleration is given by formula :
[tex]a=\dfrac{v^2}{r}[/tex]
Here,
v is the speed of the ball in circular path
r is the radius of circular path
The centripetal acceleration is inversely proportional to the radius of the circular path. To increase the centripetal acceleration by a factor of 8, the radius must decrease by a factor of 8 keeping speed constant.
Answer:
Explanation:
The formula of the centripetal acceleration is given by
[tex]a=\frac{v^{2}}{R}[/tex]
The centripetal acceleration is increased by 8 times, it means the velocity is doubled and the radius is halved.
