MHT CET Physics question
Five particles of mass 2 kg each are attached to the rim of a circular disc of radius 0.1 m and negligible mass. Moment of inertia of the system about the axis passing through the centre of the disc and perpendicular to its plane is [BHU 2003, CPMT 2004, RPMT 2006]
Answer: (B)
Solution
kg m; 1 and 2 are ten times too large and 0.2 is double. Hence the correct option is (b).
