Problem 1d. A rotating object. (1 point) An object is made of a thin rod with mass m = 0.250 kg and length 2a (@ = 0.300 m) on the y-axis and half of a thin hoop with mass M = 0.200 kg and radius a attached to the end points of the rod as shown. The object is located completely within the xy-plane. The +z-axis is perpendicular to the drawing through . The dashed line is the line y = x in the xy- plane. This is the axis of rotation of the object in this problem. Which, if any of the products of inertia is/are zero (noting that /=1, , etc.)? A:Only [, B: Only I, C:Only /. D:Only f_and [, E: 1, I., and I, are zero
