Física Universitaria (Vol. 2 | 14ta ed.): Ejercicio 21.34 (Campo eléctrico)

21.34 A point charge of +8.75 μC is attached to the underside of a frictionless horizontal table. It is connected to a point charge of -6.50 mC by a light, insulating wire 2.50 cm long. A uniform electric field of magnitude 1.85 × 10⁸ N/C is directed parallel to the wire, as illustrated in Figure E21.34. a) Calculate the tension in the wire. b) What would the tension be if both charges were negative? 💡 Like the content? ✔️ Subscribe and turn on notifications 🔔 to receive alerts every time I post a new video.
