(a) A thin rod of length 2L lies along the y axis centered at the origin. Suppose it has a charge density, λ= α|y|, where α is some constant. Find the total charge of the rod.
Added by Elizabeth F.
Step 1
The charge density of the rod is given by \( \lambda = \alpha |y| \). The rod extends from \( y = -L \) to \( y = L \). Show more…
