QUESTION 4 11 points Save Answer A proton is traveling between point 1, where the potential produced by the positive charge is 18 V, to point 2, where the potential is 2 V. Its speed, as it passes point 1, is 7.0x10# m/s . Your task is to calculate its speed when reaching point 2. a. Identify whether the proton's kinetic energy increases or decreases. (1 mark) b. Type all provided physical quantities (symbol, numerical value and unit) you need for your calculations (6 marks) c. Write the number(s) of the formula(s) from the formula sheet for modules 1-10 you use for your calculations . Do not type any formula. (1 mark) d. Write your answer for the speed. Do not type your calculations (3 marks) + N
