Find the radius of gyration and moment of inertia of a rod of mass 100 g and length 100 cm about an axis passing through its center and perpendicular its length.

(i) Here M = 100g = 0.1kg,
l = 100cm = 1m, K = ?, I = ?
M.I. of the rod about an axis through its center and perpendicular to its length is
