Work done by E field. Need helps =((. Thanks

The diagram at night shows a top view of a positively charged rod. Points W, X, Y, and Z lie in a plane near the center of the red. Points W and Y are equidistant from the rod, as are points X and Z. Draw electric field vectors at points W, X, Y, and Z. A particle with charge +q, travel along a straight line path from W to point X. Is the work done by the electric field on the particle positive, negative, or zero? Explain using a sketch that shows the electric force on the particle and the displacement of the particle. 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 X to point W. The particle travels from point X to point Z along the circular are shown. IS the done by the electric field on the particle positive, negative, or zero? Explain.

Explanation / Answer

B. A particle with charge +q0 travels along a straight line path from point W to point X.

The work done by the electric field on the particle is zero.

C. The particle travels from point X to point Z along the circulare arc shown in figure above.

The work done by the electric field on the particle is negative , because particles moving in counter-clockwise direction from X to Z.
