    How to find electric field due to a finite linear charge at its axial line ?
    If we have a charge uniformly distributed over a linear object, we can determine its electric field at any point but how we can find the same at a point, which lies on the axial line near to one of its end .
    The field is due to finite linear charge distribution and not due to an infinite one .
