Solution

The question asks for the work done to move an object along a given path in a vector field. To solve this problem, we need to calculate the work done using the formula for work in a force field, which is:

W=FdrW = \int \mathbf{F} \cdot d\mathbf{r}

where F\mathbf{F} is the force vector, and drd\mathbf{r} is the displacement vector.

Step 1: Analyzing the Image From the image, the object moves along a square path, and the forces involved are probably constant along the path segments.

Step 2: Determining the Force Let's assume the force vector F\mathbf{F} is constant throughout the path, and its components in the xx and yy directions are FxF_x and FyF_y, respectively.

Step 3: Path Analysis and Calculation The path is divided into segments along the grid lines, where we can assume the displacement in the xx and yy directions is uniform along each segment.

  1. Horizontal Segment (e.g., ABA \to B):
    Displacement drd\mathbf{r} in the xx-direction, with force FxF_x.

  2. Vertical Segment (e.g., BCB \to C):
    Displacement drd\mathbf{r} in the yy-direction, with force FyF_y.

The work done along each segment can be summed up:

  • WAB=FxΔxW_{AB} = F_x \Delta x
  • WBC=FyΔyW_{BC} = F_y \Delta y
  • Similarly, calculate for other segments.

Step 4: Summing the Work Done

Sum the work done along all segments to get the total work done. Since the image provided is unclear about the specific vector field and forces, I will proceed with the assumption that the work can be calculated as:

W=FxΔx+FyΔyW = F_x \Delta x + F_y \Delta y

where Δx\Delta x and Δy\Delta y are the distances along the xx and yy axes, respectively.


Let's calculate the work done:

  1. If the force is provided or can be assumed from the given choices, we can use that information to determine the work done.

  2. The answer choices suggest specific work values, which may correspond to specific forces applied along the path.
