Homework Statement An electron has an initial velocity of 2.5 × 106 m/s in the x direction. It enters a uniform electric field ~E = (320 N/C) ˆj which is in the y direction. The charge and mass of an electron are 1.6×10−19 C and 9.11×10−31 kg, respectively. Find the acceleration of the...

Tried with 8e9 and got it returned as wrong so hrmm, still scratching away at this.. I've tried also to do this Q=E(d+r)^2/kc (finger to any point where air breaks down) Q=E(r)^2/kc (doorknob to any point where air breaks down) Soo: E(r)^2/kc=Q=E(d+r)^2/kc But this ends up giving me...

Homework Statement On a dry winter day, if you scuff your feet across a carpet, you build up a charge and get a shock when you touch a metal doorknob. In a dark room you can actually see a spark about 5.0 cm long. Air breaks down at a field strength of 3.0 x 10^6 N/C. Assume that just before...

Oh wow. 3X completely whooshed by my head. You've saved my sanity, thank you.

Homework Statement A meter stick has two charges placed on it at the 0 mark is a charge of +1 coulomb. On the 100cm mark is a charge of +4 coulombs. Where should a proton be placed on the meter stick so that the net force due to both charges is 0. Homework Equations Kc = Coulomb const. Q=...
