Question
A massive uniform rigid circular disc is mounted on a frictionless bearing at the end E of a massive uniform rigid shaft AE which is suspended horizontally in a uniform gravitational field by two identical light inextensible strings AB and CD as shown, where G is the center of mass of the shaft-disc assembly and π is the acceleration due to gravity. The disc is then given a rapid spin π about its axis in the positive x-axis direction as shown, while the shaft remains at rest. The direction of rotation is defined by using the right-hand thumb rule. If the string AB is suddenly cut, assuming negligible energy dissipation, the shaft AE will
Options :
rotate slowly (compared to π) about the negative z-axis direction
rotate slowly (compared to π) about the positive z-axis direction
rotate slowly (compared to π) about the positive y-axis direction
rotate slowly (compared to π) about the positive y-axis direction
