B. Suppose the +q, particle travels from point W to point Y along the path WXZY as shown. Z W X 1. Compare the work done by the electric field when the particle travels from point W to point X" to that done when the particle travels from point Z to point Y. Explain. 2. What is the total work done by the electric field on the particle as it moves along the path WXZY? Explain your conclusion. 3. Suppose the particle travels from W to Y along the arc shown below. Z Is the work done by the electric field on the particle positive, negative, or zero? Explain using a sketch that shows both the electric force on the particle and the displacement of the particle 4. Suppose the particle travels along the straight path WY. Is the work done by the electric field on the particle positive, negative, or zero? Explain using force and displacement vectors. ( work done along the first half of the path to the work done along the second half.)
