    Hi Friends Please Solve my problem

    Please TEll Properly

    dq = Surface Charge
    da = Surface Area
    Radius of ring = w
    Total Radius = R
    qo = Point Charge
    Distance from Center of Ring to Point Charge = Z

    I want to know how I ca apply binomial theorem to solve the equation
    If
    Z = 0
    Z >> 0 (Very greater)
