3. Potential functions arise frequently in physics and engineering. A potential function has the property that a field of interest (for example, an electric field, a gravitational field, or a velocity field) is the gradient of the potential function (or sometimes the negative gradient of the potential function). The electric field due to a point charge of strength Q at the origin has a potential function $\phi(r) = \frac{kQ}{r}$, where $r^2 = x^2 + y^2 + z^2$ is the square of the distance between a variable point $P(x, y, z)$ and the charge, and $k > 0$ is a physical constant. The electric field is given by $\vec{E} = -\nabla \phi$, where $\nabla \phi$ is the gradient in three dimensions. 1

Suppose the consumers of tropical fruit in St. Louis litter the streets with tropical fruit peels and many children have slipped on mango pits. Clean up costs, medical bills, and pest control costs increase. The city estimates the externality to amount to $0.30 per pound of tropical fruit sold. Assume the citizens were able to vote the taxes off, so there are no taxes. 1. Is the competitive market outcome (equilibrium price and quantity) efficient? Explain.

Algorithm: Binary Algorithm for Greatest Common Divisor Input: Two positive integers $a$ and $b$. Output: A positive integer $ans$ representing greatest common divisor of $a$ and $b$. $n \leftarrow min(a, b)$, $m \leftarrow max(a, b)$, $ans \leftarrow 1$ while $n \neq 0$ and $m \neq 0$ do if $n$ is even and $m$ is even then $ans \leftarrow ans \times 2, n \leftarrow n/2, m \leftarrow m/2$ else if $n$ is even then $n \leftarrow n/2$ else if $m$ is even then $m \leftarrow m/2$ end if $n \geq m$ then swap$(n, m)$ $m \leftarrow (m - n)$ end return $n \times ans$
