A small button placed on a horizontal rotating platform with diameter 0.520 m will revolve with the platform when it is brought
yawa3891 [41]

For the position of button we can use force balance as

Friction Force = Centripetal force

so here we will have

\mu_s mg = m\omega^2 R

here we know that

R = radius of circle where button is placed

\omega = 2\pi f

f = 35 rev/min

f = \frac{35}{60} rev/s = 0.58 rev/s

\omega = 2\pi (0.58) = 3.66 rad/s

now from above equation

\mu_s(m)(9.81) = (3.66)^2(0.240)

\mu_s = 0.33

so friction coefficient will be 0.33
