A positively charged ball is dropped into a tube with another positively charged ball at the bottom. It falls a certain distance before turning around. Draw an energy bar chart consistent with this. Take the initial point to be at the top immediately after release and the final point where it turns around. Write an energy equation for this situation, indicating various distances on a sketch. State what your system is and any assumptions you needed to make. Draw qualitatively accurate force diagrams for the dropped ball for the initial and final positions. Write Newton’s 2nd Law equations for the initial and final positions
