1. Homework Statement
Find the total charge on a circular disc of radius ρ = a if the charge density is given by
ρs = ρs0 (e^−ρ) sin2 φ C/m2 where ρs0 is a constant.
Are the two limits of integration from 0 -> a for ρ and 0->2∏ for φ? In the example given in the notes, ρ varies, instead of being a constant value. Does this mean that I cannot integrate ρ in this problem?
2. Homework Equations
Q = ∫ρdS
3. The Attempt at a Solution
Q = ∫∫ρs0 (e^−ρ) sin^2 (φ) dφdρ...
