Ah, I totally ignored gravity >.< With gravity the formula is: mgh=σql/2ε+0.5mv^2 (5*10^-7)(9.81)(0.4-0.1)=(8*10^-12)(6*10^-6)(0.4-0.1)/2ε+0.5(5*10^-7)v^2 v=1.62m/s The answer is finally correct. Thanks for all the help >.<

Homework Statement A small sphere with mass 5.00×10−7 kg and charge +6.00 μC is released from rest a distance of 0.400 m above a large horizontal insulating sheet of charge that has uniform surface charge density σ = +8.00 pC/m2.Using energy methods, calculate the speed of the sphere when it is...
