1.A uniform line charge A is placed on an infinite straight wire, a distance d above a grounded conducting plane. (Let's say the wire runs parallel to the x-axis and directly above it, and the conducting plane is the xy plane.) a). Find the potential in the region above the plane. b). Find the charge density ¾ induced on the conducting plane. 2.A rectangular pipe, running parallel to the z-axis(from +infinite to -infinite), has three grounded metal sides, at y = 0, y = a, and x = 0. The fourth side, at x = b, is maintained at a specified potential V0(y) a). Develop a general formula for the potential within the pipe. b). Find the potential explicitly, for the case V0(y) = V0 (a constant). 兩題 請高手幫解!! -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.115.204.86

第一題用鏡像法..其實這兩題好像都是GRIFFITHS的例題吧@_@

照時間推算還可能是期中作業之類的-,-
