The accompanying figure shows two long, straight, horizontal wires that are parallel and a distance $2a$ apart. Both wires carry current $I$ in the same direction. Give your answer in terms of given variables ( $I$ and $a$ ) and physical and numerical constants ( ${?}_0$ and $?$ ). Figure shows two long parallel wires that are distance $2\mathrm{a}$ apart. Current flows through the wires in the same direction. Point P1 is located between the wires at a distance a from each. Point P2 is located at a distance 2 a outside the wires. magnetic field tue to long, straight wires. Use superposition principle to find the net magnetic field due to the two wires, using the right-hand rule to determine the direction of magnetic field due to each wire at point $P_1$ and $P_2$. a. What is the magnetic field at $P_1$ ? The magnetic field at $P_1$ is - (Format hint: Spell out Greek letters and use underscore ("_") for subscripts. For example, to type in ${?}_0$, type in "mu_0".) b. What is the magnetic field at $P_2$ ? The magnetic field at $P_2$ has magnitude and points - (Format hint: Spell out Greek letters and use underscore ("_") for subscripts. For example, to type in ${?}_0$, type in "mu_0".)
