1.	A wire of linear mass density lambda (kg//m) is bent intoan arc of a circle of radius R subtending an angle 2 theta_(0) at the centre. Calculate the moment o inertia of this circular arc about an axis passing through its midpoint (M) and perpendicular to its plane.
Answer» ANSWER :`I = 4 LAMBDA R^(3) (theta_(0) - sin theta_(0))`
