    Find E field for a ring of charge - Charge per length non-uniform

    I'm just having trouble visualizing why the answer is only in the i_hat. Can you help clarify this for me?

    Find E field for a ring of charge - Charge per length non-uniform

    I thought because \lambda(\phi) = \lambda_0 cos(\phi) so when you do the integral the cos doesn't pull out.

    Find E field for a ring of charge - Charge per length non-uniform

    I have to find the E field at all points on the z-axis for a ring of charge with radius = R. \lambda(\phi) = \lambda_0 cos(\phi) where 0 \leq \phi < 2 \pi I know how to do the problem when it is the charge per length is uniform but when I do the calculation for the non-uniform case I...
