Why do objects always rotate about their centre of mass?

[QUOTE="vanhees71, post: 6358030, member: 260864"] That's all fine. My point was that the "point of attack" is in general the center of mass only for gravity. If the center of charge is not the same as the center of mass it's obviously not true even for an homogeneous electric field. Of course your equation is right, but you'll get additional torque if you look at the equation for the rotation. [/QUOTE]
