A long straight wire on the z-axis carries a current of 8.0 A in the +z direction (out of the paper). A circular loop of radius 10 cm lies in the xy-plane and carries a 3.0-A current, as shown in the figure. Point P, at the center of the loop, is 25 cm from the z-axis. An electron is projected from P with a velocity of 3.0 × 106 m/s in the -x direction. What is the y component of the magnetic force on the electron at point P? (e = 1.60 × 10-19, μ0 = 4π × 10-7 T ∙ m/A)

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
