What is the moment of inertia of a square sheet of side 1 and mass per unit area u about an axispassing through the centre and perpendicular to itsplane(B)12(A) 412ul6Mul"(C)(D)126​

Answer»

μl 4/6  EXPLANATION:Given that, SIDE = L Mass per unit area = μ Total mass M=μl 2  Now, the moment of inertia is I=   MR 2/12  By perpendicular axis theorem I=I  x +I  y ​ I=2I  x ​ I=2× μl 2  ×l  2/12 I=   μl  4/6  Hence, the moment of inertia of a square sheet is   μl 4/6  ​Hope this helps you:)
