- In the image below, you see four spheres moving only under the influence of gravity. Assuming wind resistance is negligible, rank from smallest to largest the magnitudes of the net forces acting on the spheres.
- magnitude of net force on A < magnitude of net force on B < magnitude of net force on C < magnitude of net force on D
- magnitude of net force on B < magnitude of net force on A < magnitude of net force on C < magnitude of net force on D
- magnitude of net force on A = magnitude of net force on B < magnitude of net force on C < magnitude of net force on D
- magnitude of net force on A = magnitude of net force on C < magnitude of net force on B < magnitude of net force on D
- magnitude of net force on D < magnitude of net force on C < magnitude of net force on B < magnitude of net force on A
