Question

a single bead can slide with negligible friction on a wire that is bent into circular loop of radius 15 cm an in the figure. the circle is always in a vertical plane and rotates steadily about its vertical diameter with a period of 0.450 s. the position of the bead is described by the angle t that the radial line,from the center of the loop to thebead,makes with the vertical.at what angle up from the bottom of the circlecan the bead stay motionless relative to the turning circle?
