II. A stationary proton is moved from point A, where the potential is 450V, to point B, where the potential is 125V. Answer format: +1.2x10^-3 [unit] (make sure to put +/- in the number and the exponent of the notation) (If answer is zero, put 0) (Use one decimal place for final answer) TAKE NOTE: When solving, use as many decimal places as you can in computing for the values. Your answers below should not be used in calculating for other values because it is already rounded off and might affect your answer. How much work is done by the electric force? What is its speed at point B? What is the electric potential energy at point A? What is the electric potential energy at point B?
