1. There are 2 negatively charged plates opposite each other. In between them, there is a vacuum tube (50 cm long), containing only 1 electron. Assume it is completely isolated. The charge value for the plates is equivalent to 10000 electrons. Initially the single electron is directly in the center, after the initial displacement by an external electric field the electron is displaced 10 cm. r1=0.15 r2=0.25 r3=0.35 k=9.0*10^9 q1 as well as q2 = - (1.6*10^-19) n = 10001 (electrons in 1 plate + electron in the vacuum) 2. Q1: How much kinetic energy can the electron have at a max speed? What is this speed? Ee1 + Ek1 = Ee2 + Ek2 (A1- already solved, Vmax = 5.3*10^3; EK = 1.278*10^-23) Q2: Determine w (angular frequency) Q3: Determine the period T 3. How do we determine w using the velocity we calculated? We know Vmax=A root of (k/m) but then we realized that w^2 doesn't = k/m because this isn't simply SHM. We searched up and down but we can't figure out what equations we're supposed to use or how to solve this at all. Thank you.
