Electric field on the x-axis of a semicircle

  1. Jan 24, 2017 #1
    1. The problem statement, all variables and given/known data
    There's a charged semicircle, the ends of which are on the x-axis and it extends into the positive y-axis. It has uniform line charge density. I need to find the electric field at an arbitrary point on the x-axis that's not the origin.

    2. Relevant equations
    I don't know.

    3. The attempt at a solution
    I don't even know where to start. Even just starting me off would be much appreciated.

    Hello eckerm, :welcome:

    The guidelines prevent me from helping you in this state of affairs. 'Dunno' doesn't count in the PF culture. Look around a bit (hyperphysics, for example) and come back with a formula.

    And a sketch of the situation might be useful too. I for one, can't make out whaat your configuration looks like. It will be difficult to calculate the field at the points where the 'ends are on the x-axis' if I take your description literally.
