A hollow glass tulbe A thin walled hollow circuular glass tube, open at both ends, has a radius R and length & (see thef origin. The outer sides are rubbed with silk and acquire a net positive charge Q distributed uniformily. Determine the electric field at a ocation on the x axis, a distance w from the orlgin. Carry out all steps including chocking your result. Explain sach step. You may have to refer to a table of integrals. (Do this on paper. Your instructor may ask you to turn in this work.) glass tube, open at hoth ends, has a radius R and length L (see the figure). The axis of the tube lies along the x axis, with the left end at the Step 1: Since we know the electric field of a charged ring, divide the tube into rings, of thickness dx. Consider a representative ring somawhere in the middle of the tube, with its center at ex,0,0>, Draw a diagram illustrating this situation. Step 2: How much charge dq is on this ring? Write your answer symbolically. (Use any variable or symbol stated above as necassary-) 2 what is the distance from this ring to the observation location? What is the vactor from source to observation location?

Explanation / Answer

As the source is at a distance 'x' from the origin and observation location is at a distance 'w' from origin therefore the vector from source to observation location is given by (w-x,0,0)

NOTE: Try writing ( d = w-x ) in your answer rather than directly writing (d,0,0). This might be the reason that your answer is showing as wrong.
