Problem

An object is pulled through a displacement of

2\,\text{m}

by the same

10\,\text{N}

force in four different situations. The angle

\theta

between the force and the displacement is changed each time: Situation A:

\theta = 0^\circ

Situation B:

\theta = 30^\circ

Situation C:

\theta = 60^\circ

Situation D:

\theta = 120^\circ

Which situation results in the greatest positive work done by the force? a) Situation C b) Situation D c) Situation A d) Situation B
