Question
Use Gauss's law to find the field inside and outside a long hollow cylindrical tube, which carries a uniform surface charge o. Check that your answer is consistent with the general formula for the discontinuity in the electric field across a charged surface: Eabove – Epelow Then, use your answer to calculate the magnitude of the electric field a radial distance r = 14.1 from the central axis of a long hollow cylindrical tube whose radius is a = 0.34, and whose surface charge density is o = 8.5 x 10-º (all quantities are given in SI units). Enter your numerical answer into the answer-box provided. Three charges are situated at the corners of a square (side a), as shown below. How much work (in Joules) does it take to bring in another charge, +q, from far away and place it in the fourth corner if a = 5.0 m and q = 8.7 x 10-5 C? a +q•
