Q1 A spherical shell has an inner radius $R_a = 10$ cm and an outer radius $R_b = 20$ cm. It has a variable charge density $\rho(r) = \frac{0.02 \text{ C/m}^2}{r}$. What is the total charge of the shell? Give the answer in the unit mC. Q2 Two dipoles are separated from each other by a center-to-center distance $a = 1$ cm. Both have a dipole charge $q = 2 \mu C$, the distance between the charges is $d = 0.01$ cm. $d$ $a$ Calculate the magnitude of the force exerted by one dipole on the other. Give the answer in the unit N.

Calculate the leading corrections to the energy eigenvalues of the 3 lowest lying states in an infinite square well with the perturbation in the figure. Consider two-electron wavefunctions (spin and space). In the absence of the perturbation what are the energies $S_{total}$ for the lowest 4 states. What are the energies and $S_{total}$'s in the presence of the perturbation?.

Give an $\epsilon$-$\delta$ proof of the limit fact.\\ $\lim_{x\to 0} (4x+5) = 5$\\ Let $\epsilon > 0$ be given. Choose the correct answer below.\\ A. Choose $\delta = \frac{\epsilon}{5}$. Then $0 < |x - 0| < \delta \implies |(4x + 5) - 4x| = |5x| = 5|x| < 5\delta = \epsilon$.\\ B. Choose $\delta = \frac{\epsilon}{4}$. Then $0 < |x - 0| < \delta \implies |(4x + 5) - 5| = |4x| = 4|x| < 4\delta = \epsilon$.\\ C. Choose $\delta = 4\epsilon$. Then $0 < |x - 0| < \delta \implies |(4x + 5) - 5| = |4x| = 4|x| < \frac{\delta}{4} = \epsilon$.\\ D. Choose $\delta = \epsilon$. Then $0 < |x - 0| < \delta \implies |(4x + 5) - 5| = |4x| < \delta = \epsilon$.
