JEE Main Physics question
Statement 1: Moment of inertia of a circular ring about a given axis is more than the moment of inertia of a circular disc of the same mass and the same size, about the same axis. Statement 2: The circular ring is hollow, so its moment of inertia is more than the circular disc which is solid.
Answer: (B)
Solution
Both statements are factually true ( for the same mass and radius, and the ring is indeed hollow/mass concentrated at the rim). However, Statement 2's phrasing ("hollow, so MOI is more") does not precisely explain
