1. The problem statement, all variables and given/known data You're 1.5 m from a charge distribution whose size is much less than 1 m. You measure an electric field strength of 282 N/C. You move to a distance of 2.0 m, and the field strength becomes 119 N/C. Hint: Don't try to calculate the charge. Instead determine how the field decreases with distance and from that, infer the charge. 2. Relevant equations 3. The attempt at a solution All I was taught by the prof was that I need to break charge distribution into elements of dq and then integrate over the distance. However, the question does not necessarily state the distance of the distribution, which is why I think the question gives two instances of field measurements, i'm not sure how to approach the question from here. Hope that I can get a good lead on how to solve this question. Thanks.
