17.36. Set Up: For a point charge, Solve: 17.37. Set Up: The electric field of a point charge has magnitude A proton has charge Solve: (a) (b) Reflect: The electric fields inside atoms are very large. 17.38. Set Up: The weight of an electron is with The magnitude of the force on the electron due to the electric field is In part (b), the electric field of a proton at a distance r from the proton is Solve: (a) gives and (b) so 17.39. Set Up: If the axon is modeled as a point charge, its electric field is The electric field of a point charge is directed away from the charge if it is positive. Solve: (a) ions enter per meter so in a section, ions enter. This number of ions has charge (b) directed away from the axon. (c) 17.40. Set Up: The electric field of a negative charge is directed toward the charge. The net field is the vector sum of the fields produced by each charge. Point A is 0.100 m from and 0.150 m from Point B is 0.100 m from and 0.350 m from A charge q in an electric field experiences a force Figure 17.40 0.150m 0.100m 0.100m 0.250m q 2 E 1 q 1 E 2 q 1 q 2 B E 1 E 2 A (a) (b) 2 2 2 2 F S 5 q E S .
