An electron (mass of 9.110×10-31kg and charge of -1.602×10-19C) is released at rest above the surface of the earth (where g = 9.81 m/s2). A second electron directly below it exerts an electrostatic force on the first electron that exactly cancels the gravitational force. What is the distance between the two? 2. Relevant equations F=Eq F=ma F=kq1q2/r^2 3. The attempt at a solution I honestly don't know at all how to solve this. If someone could explain to me how and maybe show me the initial steps, that would be great!!
