Three different forces produce the same displacement: the vector Delta(r) starts at the left edge of your computer monitor and the tip points to the right edge of your monitor in a horizontal orientation. The first force has a magnitude of 10 N and it is pointing straight up, the second force has a magnitude of 8 N and makes an angle of 60 degrees above Delta(r) and the third force has a magnitude of 6 N and is parallel to Delta(r). Which force does the most work?
