Homework Help: Physics question help?

  1. Nov 3, 2004 #1
    Need some help on this question. My first year electronics engineering technology.
    CH. Electronic Potential and Electric Energy

    In what region of space is the potential due to a uniformly charged sphere the same as that of a point charge? In what region does it differ from that of a point charge?

    Thank you for your help.

    any region outside the sphere it is the same as a point charge so maybe you can guess the other.
