Whenever angle $(θ)$ between the force and the displacement is obtuse, i.e., $90^{\circ} < θ < 180^{\circ}$ , the work done is negative.

we know,
W $= F \times S \times c o s θ$
if $θ w i l l b e g r e a t e r t h a n 90^{0} t h e n t h e v a l u e o f c o s θ w i l l b e n e g a t i v e$
hence,the Workdone will be negative.

we know,W=F×S×cosθif θ will be greater than 900then the value of cosθ will be negativehence,the Workdone will be negative.
