Three particles each of mass 10g are situated at the three corners of an equilateral tringle of side 5cm. Determine the moment of interia of this system about an axis passing through one corner of the tringle and perpendicular to the plane of the tringle

Dear Samrat,
Moment of inertia due to mass passing through the axis is zero .
Moment of inertia due to other 2 mass = 2.m.r2= 2.10-2.25.10-4= 5 x 10-5 kg.m2
Thanks and Regards
