Three charges (-5C, 3.5C, -2C) are on the x-axis at 0, 5m, and 10m respectively. what is the electric field (magnitude and direction) at the following points:
(0, 5m)
(3m, 10m)
(-5m, -10m)
If a 1C charge with a mass of 0.1 kg were placed at each of those positions and let go, what is the acceleration it would undergo (amplitude and direction). (There is no gravity in this problem)
