Setting the Stage: A uniform sphere has a mass of 100 kilograms and a radius of 10 meters. It is located at [0,0,0] It is in static equilibrium. We are in constant time. We are in a vacuum, there is no gravity, friction, or any other forces to act upon our sphere. We are using a coordinate system compatible with OpenGL; right-hand. You are looking down the negative Z axis and can see the sphere in front of you. Z', A force of [1,0,0] Newtons, is applied at point, P', [0,0,10]. Stating the Obvious for Clarity: This will create a counter-clockwise rotation. Z' is tangential to the surface of the sphere. The Question: Finding Torque is no problem. A cross product and some work with the moment of inertia. That is not the question. Q1) How does one find the resulting linear acceleration? Q2) Is the resulting linear acceleration inversely proportional to the distance from the center of mass the Force is applied?
