Hi urduworld! Welcome to PF!

(btw, never bump your questions in the first 24 hours … people are much more likely to answer a thread with 0 replies , and half PF's members are asleep now anyway! )
Hint: divide the rod into slices of thickness dy and charge Qdy/L, find the force from each slice, and integrate from x to x + L …

what do you get?
