A uniform thin rod is bent in the form of closed loop `ABCDEFA` as shown in the figure. The ratio of moment of inertia of the loop about `x`-axis to that about `y`-axis is A. Greater than `1`B. Less than `1`C. Equal to `1`D. Equal to `0.5` |

Answer» Correct Answer - B Moment of inertia of semicircular poritons about X and Y axes same. `I_(X)=I_(Y)=mR^(2)` Then MI of straight portion about X-axis is zero `therefore I_(x)ltI_(y)` (or) `(I_(x))/(I_(Y))lt1` |
