1. The problem statement, all variables and given/known data A positively charged bead having a mass of 1g falls from rest in a vaccum from a height of 5m in a uniform vertical electric field with a magnitude of 1 x 10^4 N/C. The bead hits the ground at a speed of 21 m/s. Determine a) the direction of the electric field (upward or downward), and b) the charge on the bead. 2. Relevant equations E=kq/r^2 F=kq1q2/r^2 3. The attempt at a solution First of all, I want to make sure that my diagram is correctly drawn. I'm sorta of confused on how the electric field and vacuum are positioned. http://img125.imageshack.us/my.php?image=52diagramhd1.png Thanks!
