A Level Physics Electric Fields 1 (Answers) Total Marks:/30 AQA, Edexcel, OCR A Level Solution: The force experienced per unit positive charge at that point. Solution: Similarities: both have dependence on product of two charges/masses; both have inverse square law dependence on distance; point charges/masses produce radial fields. Differences: whilst gravitational fields are always attractive, electric fields can also be repulsive. 1. Total for Question 1: 13 (a) Define the electric ...
