Two large parallel plates are separated by a distance $d = 0.050 \, m$ and are charged with surface charge densities $\sigma_1 = +4.00 \, \mu C/m^2$ and $\sigma_2 = -2.00 \, \mu C/m^2$. The space between the plates is initially evacuated, but then it is filled with a dielectric material that has a dielectric constant $\kappa = 2.5$. a) Calculate the electric field $E_0$ between the plates when the space is evacuated. b) Determine the new electric field $E$ between the plates after the dielectric is introduced. c) Calculate the potential difference $V$ between the plates with and without the dielectric. d) If the dielectric is partially removed, leaving a thickness $d_1 = 0.030 \, m$ of dielectric and $d_2 = 0.020 \, m$ of vacuum, what is the new electric field $E_{new}$ in the space between the plates?

- Combining the first three equations gives the Euler equation: \[ u^{\prime}\left(c_{0}\right)=\frac{1}{q} \beta \sum_{i=1}^{n} \pi_{i} u^{\prime}\left(c_{1 i}\right) \equiv \frac{1}{q} \beta E\left[u^{\prime}\left(c_{1 i}\right)\right], \] which means that at the optimum, the consumer's marginal utility at period 0 is equal to the discounted expected marginal utility from consuming $ \frac{1}{q} $ units in period 1 . Note that here $ \frac{1}{q} $ can be regarded as the return on the investment. - If $ u(c)=\ln c $ and $ v(n)=\ln (1-n) $, we have \[ c_{1 i}=w_{i}\left(1-n_{i}\right), \] combining it with the budget constraint $ c_{1 i}=a+w_{i} n_{i} $ : \[ c_{1 i}=\frac{a+w_{i}}{2} \] Using the Euler equation and $ c_{0}+a q=I $, we can solve for optimal $ a $ given $ q $ : \[ \frac{q}{I-a^{*} q}=\beta \sum_{i=1}^{n} \pi_{i} \frac{2}{a^{*}+w_{i}} \]

In the nation of Winknam, the capital share of GDP is 30 percent, the average growth in output is 4.0 percent per year, the depreciation rate is 6.0 percent per year, and the capital-output ratio is 6.0. Suppose that the production function is Cobb- Douglas and that Winknam has been in a steady state. Round answers to two places after the decimal when necessary. c. Suppose that public policy alters the saving rate so that the economy reaches the Golden Rule level of capital. What will the marginal product of capital be at the Golden Rule steady state ($MPK_{gold}$)? $MPK_{gold} = $ d. What will the capital-output ratio be at the Golden Rule steady state ($\frac{K}{Y_{gold}}$)? $\frac{K}{Y_{gold}} = $ e. What must the saving rate be to reach the Golden Rule steady state ($s_{gold}$)?
