Question

The moment of inertia of a hollow cylinder is
Options
A ½ MR²
B ½ M(R₁² + R₂²)
Correct Answer
C ⅖ M(R₁² + R₂²)
D ½ M(R₁² + R₂²)
Correct Answer

Option B is the correct answer.

Detailed Explanation

For a hollow cylinder (or thick-walled cylinder), the moment of inertia about its axis is I = ½ M(R₁² + R₂²), where R₁ is inner radius and R₂ is outer radius.

Hint

Recall the standard formula for hollow cylinder moment of inertia.
