Homework Help: Electric Field at Ro, Phi, and Z Help!

  1. Feb 12, 2010 #1
    A 2[[tex]\mu[/tex]C] point charge is located at A(4,3,5) in free space. Find E[tex]\rho[/tex], E[tex]\phi[/tex], and Ez at P(8,12,2).

    I know I have to start off in rectangular, convert to cylindrical coordinates. I know how to find the R vector and |R|.

    Since it says there is a point charge, do I need to integrate anything? How would I find the 3 different components?

    Welcome to PF!

    Hi akhdz! Welcome to PF! :smile:

    (have a mu: µ and a rho: ρ and a phi: φ :wink:)
    (No, no integration needed.)

    What is the magnitude and direction of E?

    What are Ex Ey and Ez ?

    What are the directions of eρ and eφ ? :smile:
