1. An electron with a speed of 3.0 x 106 m/s moves into a uniform electric field of 1000 N/C. The field is parallel to the electron's motion. How far does the electron travel before it is brought to rest.
I read the part of the text related to electric fields but I saw nothing that related it to the velocity of particle.
2. An electron is released a short distance above Earth's surface. A second electron directly below it exerts an electrostatic force on the first ele- just great enough to cancel the gravitational force on it. How far below the first electron is the second?
Using Fg = G m1m2/r2 do I use this formula to find out the gravitational force and then set it equal to the electrical force? I'm a little confused on how to approach this.
