An electron enters the region of a uniform electric field, with v1=3*10^6 m/s and E=200N/C. The horizontal length of the plates is 0.100m 1. Fine the acceleration of the electron while in the field. 2. If the electron enters the field at a time t=0, find...

Three negatively charged sphere, each with a charge of a 4*10^-6C, are fixed at the vertices of an equilateral triangle whose sides are 20cm long. Calculate size and direction of the net electric force on each sphere.
