1.	A sphere of mass 10 kg and radius 0.5 m rotates about a tangent. The moment of inertia of the sphere is
Answer» 5 kg `m^(2)` `2.7` kg `m^(2)` 3.5 kg `m^(2)` 4.5 kg `m^(2)` Solution :MOMENT of INERTIA about tangent = `I+ MR^(2) = (2)/(5) MR^(2) + MR^(2) = (7)/(5) MR^(2) = (7)/(5) XX (10) xx (0.5)^(2) = 3.5 kg m^(2)`
