. Three rings each of mass M and radius R are arranged as shown in the figure. The moment of inertia of the system about YY' will be
Best Answer
Ans: D
Sol: M.I of system about YY'= I1+I2+I3
where I1 = moment of inertia of ring about diameter, I2 = I3 = M.I. of inertia of ring about a tangent in a plane
