A turntable of radius \(0.320 \mathrm{~m}\) is fitted with an electromagnet that causes steel objects to stay in place on the table. A triangular mark on the rim shows the rotational position of the table relative to the surroundings (Figure P11.88). The turntable completes one rotation in \(0.360 \mathrm{~s}\), and the rotation is counterclockwise in the view shown in the figure. A \(0.125-\mathrm{kg}\) steel rod of length \(0.160 \mathrm{~m}\) is placed on the table so that one end is at the center and the rod is oriented radially outward, as shown in the figure. The electromagnet is switched on, and the turntable is started. After the table reaches its steadystate rotational speed, the electromagnet is switched off at an instant when the rod lies along the positive \(x\) axis. Describe the ensuing motion of the rod.
