MCQ
The theorem of perpendicular axes is applicable for:
- ✓Only planar bodies.
- BOnly regular shaped bodies.
- COnly three dimensional bodies.
- DNone of the above.
✓
Answer
Correct option: A.
Only planar bodies.
Theorem of perpendicular axes is applicable for planar bodies only.
We generally use this theorem for regular shaped bodies but it could be applied to irregular shaped bodies as well.
