Work done by the applied force
`" " "W=Fs cos theta=Fs cos 0^(@)=Fs (therefore cos 0^(@)=1)`
`i.e. " " "W=Positive"`
(b) The gravitational force acts inm download direction and displacement in upward direction therefore angle between them is `theta=180^(@)`
Work done by the gravitional force
W=Fs cos `180^(@)=-Fs`
