Why is force inversely proportional to square of distance?
Why is force inversely proportional to square of distance? This is because the force acts uniformly in all directions from the point source and conserves the energy over the entire surface surrounding the point object. Since the surface is a sphere the area of the sphere is given as 4πr2. What is the inverse square […]
