options are-
1)0,as it rotates about its centre of mass
2)4mL^2
3)1/4mL^2
4)mL^2
In the left image is shown an ancient hunting weapon the bolas.In the right image is a"modern interpretation"and when thrown the four masses rotate about the center of mass point P

Treating the mass size to be small compared to the distance that each mass is from the pivot point allows you to evaluate the rotational inertia of the modern bolas using the discrete method to be
