Answer:B
Explanation:
Given
speed of car [tex]v=10 m/s[/tex]
mass of clump [tex]m=0.5 kg[/tex]
Radius of car tire [tex]r=0.2 m[/tex]
Since the tire is rotating about axle so a centripetal force is acting constantly on each particle towards the center of tire.
Centripetal force is given by
[tex]F_c=\frac{mv^2}{r}[/tex]
where [tex]m=mass\ of\ element [/tex]
[tex]v=speed[/tex]
[tex]r=distance\ from\ center[/tex]
[tex]F_c=\frac{0.5\times 10^2}{0.2}[/tex]
[tex]F_c=250\ N[/tex] (inward)
