A proton is acted on by an uniform electric field of magnitude 183 N/C pointing in the positive x direction. The particle is initially at rest. (a) In what direction will the charge move? (+x, -x, +y, -y, +z, -z direction) (b) Determine the work done by the electric field when the particle has moved through a distance of 3.55 cm from its initial position. ______J (c) Determine the change in electric potential energy of the charged particle. _______J (d) Determine the speed of the charged particle. _______ m/s
