E2 has a charge Q2 three times greater than that of E1, where Q1 = + 4×10^(−8) C. When E2 approaches E1, the spring undergoes a deformation x = 3 mm and the system reaches equilibrium, as shown in the diagram. It is known that E1 has a mass m = 3 g and that the distance separating the spheres corresponds to d = 40 mm. Ignoring the dimensions of the spheres, calculate, in N/m, the value of the spring constant. ================== Follow us on social media: 📱 Instagram:   / thalesquirino   📱 Twitter: https://x.com/fisiquei Check out the complete playlist of UERJ Resolution 2024: 👉   • UERJ 2024 - Em um experimento, dois relógi...   Professor Thales Quirino Medeiros ================== #ENEM #physics #medicine #studies #education
