16. Preflight 2.6 A B X Y Compare the ratio of charges Q A / Q B 1) Q A = 0.5Q B 2) Q A = Q B 3) Q A = 2 Q B A B X Y
17. Preflight 2.8 The magnitude of the electric field at point X is greater than at point Y 1) True 2) False A B X Y
18. ACT: E Field Lines Compare the magnitude of the electric field at point A and B 1) E A >E B 2) E A =E B 3) E A <E B A B

20. Preflight 2.10 "Charge A" is actually a small, charged metal ball (a conductor). The magnitude of the electric field inside the ball is: (1) Negative (2) Zero (3) Positive A B X Y
First get magnitude and direction for one, have students do the other, then say its math, then decompose using f_x = F x/r, f_y = f y/r Perhaps need to show this can be done with cosine and sine too. Preflight: What is direction of force on third charge due to dipole

If a tree falls in the forest, and no one is around to hear it, does it make a sound?

After field lines up ask to compare efield at two points of equal distance
