Compute each part of given problem:
Problem: A long, straight cylindrical rod is uniformly charged with static electricity and generates an electric field. The field has strength of 7.50N/C at a distance of 1.00m from the center of the rod.
Part A: What is the strength of the field 2.00m from the center of the rod?
Part B: What is the strength of the field 10.0m from the center of the rod?
I am having a hard time understanding these questions. So if you answer please explain how you found the answers.
