Physics 202: Extra Credit 1 Due 25" Jan in Class Electric Field Superposition Name: Full extra credit will result in 0.25% being added to your class grade. This extra credit requires knowledge of calculus and involves using the superposition principle to determine the electric field. Working in groups is strongly encouraged but you must show your own work to get full credit. You may ask me for hints and/or help. Complete 100% accuracy is not necessary for full credit - if I see that your problem-solving strategy is correct and the only mistakes you make are minor, you will receive full credit. An electric dipole consists of two point charges of equal magnitude, but opposite sign, separated by a short distance. The dipole is electrically neutral, but due to the separation of its charges gives rise to an electric field in its vicinity. Many molecules have charge distributions which can be approximat ed as an electric dipole, water being one of the most common. Given an electric dipole as shown below, calculate the electric field at the point P. Hint: Start from Coulomb's Law A-9 2d Page 1 of I
