Concept explainers
You’re 1.44 m from a charge distribution that is well under 1 cm in size. You measure an electric field strength of 296 N/C due to this distribution. You then move to a distance of 2.16 m from the distribution, where you measure a Held strength of 87.7 N/C. What’s the net charge of the distribution? Hint: Don’t try to calculate the charge. Determine instead how the field decreases with distance, and from that infer the charge.
