Find the magnitude of the gravitational field a distance r from an infinitly long uniform thin rod whose mass per unit length is (lamda)
Homework Equations
The Attempt at a Solution
Need some clarification really
i know
dgx=-Gdm/r2
r=r2-r1
lamda=m/L
i substituded them in and intergrated
so to finally get
=-GM/r22-r12
