    Two lenses of same mass and same radius are given. One is convex and other is concave. Which one will have greater moment of inertia, when rotating about an axis perpendicular to the plane and passing through the centre?

    Answer:

                    The concave lens will have greater moment of inertia because the concave lens is thin at its centre and its mass is more concentrated at the outer edge.
