Question

In an arrangement four particles, each of mass 2 gm are situated at the coordinate points (3,2,0) (0,0,0) and (-1,1,0). the moment of inertia of this arrangement about the Z-axis will be.?

Answer 1

Hey u gave the coordinates of only 3 particles..

Answer 2

For each particle, the moment of inertia is the distance from the z-axis squared times its mass (x^2 + y^2)*m. The total moment of the inertia is the sum of these quantities.
