1. The problem statement, all variables and given/known data An electron is released from rest in a weak electric field given by = -2.70 10-10 N/C [PLAIN]http://www.webassign.net/images/lowercase/jhatbold.svg. [Broken] After the electron has traveled a vertical distance of 1.4µm, what is its speed? (Do not neglect the gravitational force on the electron.) 2. Relevant equations I know that F_E = qE, and F_q = mg, as well as W_E= qEh, and W_G = mgh also, v2=v02+2aΔy but I'm not sure how im supposed to actually combine all of these equations to get the answer 3. The attempt at a solution If I find the accelerations from gravity and the electrical field I get: FE=qE=1.602*10-19*-2.4*10-10 aG=9.81 a=FE/m+9.81 = -52.01 v2=v02+2aΔy, so v2=2(-52.01)(1.4*10-6) v = 0.01405, which isn't correct. I didn't use the work equations because we haven't talked about work at all in class, so I figured we wouldn't need those equations.
