1.	The figure shows a uniform rod lying along the X-axis. The locus of all the points lying on the XY-plane, about which the moment of inertia of the rod is same as that about O is
Answer» an ellipse a circle a parabola a STRAIGHT line Solution :From theorem of parallel axis, MOMENT of inertia about an axis PASSING through a distance `l//2` from centre in all DIRECTIONS will have moment of inertia `(ml^(2))/(3)`. All such POINTS at same distance from centre will lie in a circle.
