[QUOTE="Orodruin, post: 6002996, member: 510075"] You need to use the information you are given on how much the spring extends in the absence of an electric field (supposedly by the action of gravity alone). What does this tell you about the spring? How can you use this to determine the electric force on the ball using the other information that you are given? [/QUOTE]
