Moment of inertia of an ellipse shaped wire of mass ‘m’, semimajor axis ‘a’ about an axis passing through the centre and perpendicular to the plane of wire can be:
(A) ma2
(B) 1.2 ma2
(C) 1.4 ma2
(D) 0.6 ma2
Correct option (D) 0.6 ma2
Explanation:
Moment of inertia of the ellipse should be less than that of a circular ring of radius ‘a’.
