Rotational Motion Question 71

Question: The moment of inertia of a thin uniform rod of mass M and length L about an axis passing through its mid-point and perpendicular to its length is I0 . Its moment of inertia about an axis passing through one of its ends and perpendicular to its length is

[AIPMT (S) 2011]

Options:

A) I0+ML2/4

B) I0+2ML2

C) I0+ML2

D) I0+ML2/2

Show Answer

Answer:

Correct Answer: A

Solution:

  • The theorem of parallel axis for moment of inertia.

    I=ICM+Mh2

    I=I0+M(L2)2

    I=I0+ML4
