    Hi Friends I am student of BsCs- 1st Semester,

    I am facing problem to solve a question of physics. I have tried my best to solve it but I am fail, can any one do it for me I will thank to him.

    Here Is The Question

    Find the force on a positive point charge q located a distance x from the end of a rod of length L with uniformly distributed positive charge Q. See Fig



    This Question Is Taken From Physics Vol 2—Edition fifth by
    David Haliday (university of pittsburg)
    Robert Resnic

    Welcome to PF!

    Hi urduworld! Welcome to PF! :smile:

    (btw, never bump your questions in the first 24 hours … people are much more likely to answer a thread with 0 replies :wink:, and half PF's members are asleep now anyway! :zzz:)
    Hint: divide the rod into slices of thickness dy and charge Qdy/L, find the force from each slice, and integrate from x to x + L …

    what do you get? :smile:
