[QUOTE="Baumer8993, post: 4503986, member: 457549"] [h2]Homework Statement [/h2] [url]http://imgur.com/VzZjSEH[/url] I took a screen shot so I did not leave anything out. [h2]Homework Equations[/h2] Surface area, and volume of a sphere. [h2]The Attempt at a Solution[/h2] I am trying to find the linear charge density from the charge volume density. I got it explained from a friend. It was right, but made no sense. He did it by taking the volume density, and multiplying it by the charge volume density by pi, and (outer r[SUP]2[/SUP] - inner r[SUP]2[/SUP]). So he did -657 * pi * (.042[SUP]2[/SUP] - .026[SUP]2[/SUP]) Can someone explain to me how this is right? [/QUOTE]
