**Summary: ** Hello students to find the coefficient of friction, we will equate the frictional force to the centrifugal force. So the frictional force would be equal to the centrifugal force. Now the frictional force is equal to New times. And so in here is just a simple case where the coin is resting on the table so it will be equal to MG. And the centrifugal forces. M omega squared R. So um will get canceled and now we have Nu equals omega squared R. Divided by G. Now what is the omega here? So the angular velocity is given to us in rpm. So let us convert this into Radian per second. So first this 33 rpm would be equal to 33 divided by 60 rotations per second and no one rotation contains two by radiance. So this will be equal to 33 times to fight You wanted by 60 Iranian per second. No. So let us write, put this value in here. So we have Omega will be equal to 66 by divided by 60 squared And the radius is 15 cm which will be written as zero 15 m. And then it will also be divided by G. Which is equal to 9.8. Now let us calculate so on calculating we will find that nu is equal to 0.1815. So this is the final answer. I hope you understood. Thank you
