7 A rigid square is made up of four identical light massless rods of length a and two light diagonal rods as shown in the figure Four small objects of mass m 2m 3m and 4m are attached to the four corners of the square as shown a Now the system is rotated with an angular velocity o about an axis through A the center of the system perpendicular to the plane of the square Find the rotational kinetic energy of the system b If the system is now rotated about an axis through the rod connecting the two masses 2m and 4m with angular velocity w find the new kinetic energy of the system 4m 3m a O a a m a 2m c Compare the results from a and b and make a statement as to why they are the same or different depending on your result
