A uniform rod of length L and mass M can rotate about one end. Its moment of inertia is:
A.ML²
B.½ML²
C.¼ML²
D.⅓ML²
Explanation
Core Concept
For a uniform rod rotating about one end, the moment of inertia is I = ⅓ML² (derived from integration of dm·r² over the length of the rod).
Correct Answer
D⅓ML²
