Charge is distributed along the spiral with polar equation \(r=\theta\) for \(0 \leq \theta \leq 2 \pi\). The charge density is \(ho(r, \theta)=r\) (assume distance is in centimeters and charge in units of \(10^{-6} \mathrm{C} / \mathrm{cm}\) ). Use the result of Exercise 60 (a) to compute the total charge.
