4. How many electrons pass by a point every second if a 0.400-amp current is flowing? (e = -1.602 x 10-19 C) O 2.50 x 1018 e O 1.60 x 10 Be 6.40 x 1020 e O 1.25 x 1019 e6. Assuming you have a point charge in a powerful and constant electric field, what is the relationship between the electric field and the electric potential energy? O E= PEelectric O E = P Electric O E = P Eelectric O E = P Electric? d14. One electron is separated from another electron by a distance, d. The electrostatic force between them is +9.24 x 10-26 newtons. How far apart are they? (Coulomb's constant is 9.0 x 10 Nm-/Cq; e = -1.602 x 10- 19 C) 5.0 x 10' cm O 0.050 cm O 5.0 x 10" cm O 5.0 cm22. The current leaving a battery is 0.5 A. It travels through a 100 Ohm, 200 Ohm, and 300 Ohm resistors all in series. What is the current right before it comes back to the battery? O 0.5 A O 0.0008 A O 0.005 0.0 A
