Question
NT5J-RT108: ROTATING CYLINDERS-NET FORCE MAGNITUDE Four identical small cylinders rest on a circular horizontal turntable at the positions shown in the top view diagram at right. The turntable is rotating clockwise at a constant angular velocity. Rank the magnitude of the net force on the cylinder at the positions on the turntable indicated in the diagram Greatest 1-2 3 4 Least Turntable rotating clockwise-top view OR, The magnitude of the net force on the cylinder at these positions is the same but not zero. OR, The magnitude of the net force on the cylinder at all of these positions is zero. OR, The ranking for the magnitude of net force on the cylinder at these positions cannot be determined Explain your reasoning.Explanation / Answer
Net force :T=S>P>R
Net centripetal force is required for moving in a circular region(in horizontal direction directed towards center) as in vertical direction Normal reaction N=mg so force =0, for circular motion F=m*v*v/r=m*rw*rw/r=m*w*w*r
As angular velocity is same for all greater the distance from center greater the force required
