For example, let’s consider a thin infinite sheet whose density depends only on the radial distance r from the center of the plate, σ(r) = ae−r/b . Find the total mass of the infinite r sheet. Hint:

For example, let’s consider a thin infinite sheet whose density depends only on the radial distance r from the center of the plate, σ(r) = ae−r/b . Find the total mass of the infinite r sheet. Hint: you should use polar coordinates to solve this problem, where dA = rdrdθ, where integrating over θ should […]
