3. A point charge +2q is placed at the origin. Two additional point charges -q are placed symmetrically about the origin on the x axis each at a distance a from the origin. (a) Determine the magnitude and direction of the electric field at point P which lies on the positive x-axis beyond the -q charge at the coordinate (x, 0). (b) Simplify your expression for the electric field at P in the limit that a is small compared to x. Hint: You may use the small $a/x$ expansion $$\frac{1}{(x+a)^2} \approx \frac{1}{x^2} - \frac{2a}{x^3} + \frac{3a^2}{x^4} + ...$$ (c) Determine the magnitude and direction of the electric field at point R which lies on the positive y-axis at the coordinate (0, y). (d) Simplify your expression for the electric field at R in the limit that a is small compared to y. Hint: You may use the small $a/y$ expansion $$\frac{1}{(y^2 + a^2)^{3/2}} \approx \frac{1}{y^3} - \frac{3a^2}{2y^5} + ...$$

A cylindrical wall has a temperature of 800 °C on the inside and is exposed to air and room surfaces at 20 °C on the outside. If the wall has an inside radius of 0.25 m, thickness of 10 cm, height of 0.5 m, and thermal conductance of 0.5 W (m-K), and the exposed outside surface has an emissivity of 0.8 and convection coefficient of 15 W (m?²K), (i) how much heat is transmitted through the wall, and (ii) what is the temperature of the exposed outside of the wall?
