Hi everyone I'm kinda new here, your support will really be appreciated ! :D
1. Homework Statement
Let's say the cylinder has radius R, and height T.
U = ∫GmdM/x
My attempt is shown in the picture, I took a tiny element of the cylinder with vertical distance y, and horizontal distance r from the particle, then I used integral. am I doing this right ? I think there's something odd with the "y" there. Should I range the y until the upper surface of the cylinder only?
