1. The problem statement, all variables and given/known data Find the work done by a force acting in the direction 2i - 5j + k in moving a particle from (3, 3, 1) to (1, 2, 4). 2. Relevant equations 3. The attempt at a solution I just found the displacement vector (2,1,-3) and did the dot product with the force vector. So my answer as an integer, was negative 4. Does that sound correct?
