If a force is applied at centre of mass the object will only translate and not rotate. Can anyone proove this mathematically?

Torque is the cross product of the vector from the center of mass to the point where the force is applied (r), and the force. If r is zero, or r is parallel to the force, there will be no torque, and so no rotational force.
