A proton is acted on by a uniform electric field of magnitude 233 MC pointing in the negative y direction. The particle is initially at rest. __La_)__1_n__v_vhat direction will the charge move? (b) Determine the work done by the electric eld when the particle has moved through a distance of 3.05 cm from its initial position. E (c) Determine the change in electric potential energy of the charged particle. J H (d) Determine the speed of the charged particle. m/s H
