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 :

Options

A. `ma^(2)`
B. `1.2 ma^(2)`
C. `1.4 ma^(2)`
D. `0.6 ma^(2)`

Answer

D

Explanation

Moment of inertia of the eliipse should be less than that of a circular ring of radius 'a' Hence : (D) is the suitable option.
