Main Question or Discussion Point
For the diagram below, is it wrong?
They have calculated the work done from i to f, using the force that is cross sectional to the particle.
Shouldn't the force in the direction of the path be the the force x cos theta.
They have summed the force that is not in the direction of the path?
