The field must be dated and entered as a six- or eight-digit date. The variation of electric field (E) with distance (r) is shown in the figure below. Figure 7.8. Field due to a uniformly charged infinitely plane sheet. An electric field's intensity near a plane sheet of charge: E = /2 0 K. Here, is surface charge density. It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview Questions. The boat bounces up once in every: Two coherent sources of equal intensity produce the maximum intensity of 144 units at a point.
