The radius of gyration of a uniform rod of length L about an axis pass

1.	The radius of gyration of a uniform rod of length L about an axis passing through its centre of mass is
Answer» `(L)/(SQRT(12))` `(L^2)/(sqrt(12))` `(L)/(sqrt3)` `(L)/(SQRT2)` Solution :`I = Mk^(2) = (ML^(2))/(12) THEREFORE K = (L)/(sqrt(12))`
