MHT CET 2023 Physics question
A thin wire of length 'L' and uniform linear mass density 'm' is bent into a circular coil. The moment of inertia of this coil about tangential axis and in the plane of the coil is
Answer: (B)
Solution
The mass of the ring is (linear density times length) and its radius follows from , so . Moment of inertia of a ring about a diameter is . By the parallel axis theorem, about a tangent in the plane of the ring: $I =
