Moment of inertia of a point mass:
The perpendicular distance of particle a from the x-axis is r.
Find the moment of inertia Ix of particle a with respect to the x axis (that is, if the x axis is the axis of rotation), the moment of inertia Iy of particle a with respect to the y axis, and the moment of inertia Iz of particle a with respect to the z axis (the axis that passes through the origin perpendicular to both the xand y axes)
Express your answers in terms of m and r separated by commas.
