How Does Charge Distribution Affect Electric Field in a Ring?

[QUOTE="Simon Bridge, post: 5576677, member: 367532"] There is too much missing from the problem statement to complete the assignment. ie. What is the orientation of the ring? Is it in the x-y plane? Where are we supposed to find the ##\vec E## field? only in the x-y plane? (we are only asked for x,y components). ... you mean you tried to find ##dE_x## and ##dE_y## in terms of ##\theta## The reasoning usually goes like this: The electric field element ##d\vec E## due to the charge element ##dq## on the ring between ##\theta## and ##\theta +d\theta## is given by ... etc. Looks like you have done the calculus wrong.
