Homework Help: Electric Field

  1. Jan 20, 2008 #1

    I need help with the following question for parts (iv) and (iiv). I was also wondering if anyone can check my working for parts (i) to (iii). You can assume that the numbers punched into the calculator is correct if you like.

    Many thanks. (:

    1. The problem statement, all variables and given/known data

    2. Relevant equations

    [tex] E=\frac{Q}{4\Pi\epsilon_{o}\\r^{2}}[/tex]
    [tex] E_{p} = q.V [/tex]
    [tex] V=\frac{Q}{4\Pi\epsilon_{o}\\r}[/tex]

    3. The attempt at a solution
