you can derive it using super position theory where you take a very small length of the line dl and treat it as a point charge dq where dq = (Q/L)dl , find the electric feild due to this point charge using Coloumb's law and then integrate the answer over the total length of the rod
for the ring it's similar but change your differential length and the integration limits
Thank you very much for posting this I have been having trouble with Electric field due to a ring. you have helped me a lot thank you for your time Sir.
you don't have to memorize these long equations my friends

Can you show how you derived those equations?
