Question

M.I. of an elliptic disc about major axis is​

Answer 1

Answer:

we know that the moment of inertia of an circlar disc of uniform mass distribution of mass 'm', radius 'r' about its axis is

2

mr

2

Since, For an elliptical disc of uniform mass distribution of mass 'm', semi major axis 'r', mass distribution is closer to axis so its moment of inertia will be less than

2

mr

2

.

Therefore, D is correct option.
