1 7. Explain the circumstances that enable a particle to move undeflected with uniform motion through an electric field if it is given an initial velocity perpendicular to the electric field. Assume the electric field is the only field present. 8. Diagrams below show the initial position and the velocity vector of a charged particle within a uniform electric field. (2 a. On the diagram above, sketch a free-body diagram showing the net force that acts on the particles as well as the path of the particle OR describe the path in words in the answer area below. 20 Physics 30
