Interpreting Graphics

The photograph in Figure 2.1 shows multiple images that were created by

multiple reflections between two flat mirrors. What conclusion can you make

about the relative orientation of the mirrors? Explain your answer.

Find the magnetic field a distance r from the center of a long wire that has radius a and carries a uniform current per unit area j in the positive z direction.

Which of the following are guidelines to follow for obtaining accurate observations

Charge is distributed along the entire x-axis with uniform density λ. how much work does the electric field of this charge distribution do on an electron that moves along the y-axis from y = a to y = b? (use the following as necessary: a, b, ε0, λ, and q for the charge on an electron.)
