Moment of Inertia (M.I.) of four bodies having same mass ‘M’ and radius ‘2R’ are as follows:
I₁= M.I. of solid sphere about its diameter
I₂ = M.I. of solid cylinder about its axis
I₃ = M.I. of solid circular disc about its diameter
I₄ = M.I. of thin circular ring about its diameter
If 2(I₂ + I₃) + I₄ = x. I₁ then the value of x will be _________ .
