A ceiling fan has a diameter (of the circle through the outher edges of three blocks ) of `120 cm` and rpm `1500` at fall speed consider a partical of mass `1g` stiking at the outer end of a blade.
a. How much force does it experience the fan runs at falll speed ?
b.Who exerts this force on the partical ?
c. How much force does not the particle exert on the blade along its surface?

Explanation

a. Force on the particle when the fan is at fall speed
`F_(n)= m omega^(2)R = ((1)/(1000)) ((2 pi xx 1500)/(60))^(2) ((60)/(100)) = (3)/(2) pi^(2) N`
b. The friction force excets this force
c. `F_("particle") = F_(n) = (1)/(2) pi^(2)`
