I tried u-sub, and then replaced y2 and dy for terms of u. I further simplified, but soon after, got stuck on how to integrate in terms of u. Work is shown below. Again, this is from a prior problem, and the work is shown up until the...
Okay, so we need to find the potential of this rod. "The electric potential due to a single charged particle at a distance r from that particle is V = kq/r, where k is the Coulomb constant." And because it is not a point, we need to integrate it as a non-uniform charge distribution. This means...
Here are the pictures that were supposed to be in the original post: One of the problem, and two of the work.
Can you see them now? My efforts stemmed from working with differential elements of charge, and setting up an integral involving the electric potential equation I gave in the original...

A rod of length L lies along the positive y-axis from 0<=y<=L, with L = 0.400 m. It has a positive nonuniform linear charge density (charge per unit length) λ = cy2, where c is a positive constant and has a numerical value of 8.00 x 10-7. (a)...
