# What is the angle between the force and displacement in case work done is:- a) positive b) negative c) zero

Dear Student ,

When the work done is positive then , angle between force and displacement is $\theta =0\xb0$ ,

$W=F\xb7s=Fs\mathrm{cos}\theta =Fs\mathrm{cos}0\xb0=Fs=+ve$

When the work done is negative then the angle between force and displacement is , $\theta =180\xb0$ ,

$W=F\xb7s=Fs\mathrm{cos}\theta =Fs\mathrm{cos}180\xb0=-Fs=-ve$

When the work done is zero then the angle between the force and displacement is , $\theta =90\xb0$ ,

$W=F\xb7s=Fs\mathrm{cos}\theta =Fs\mathrm{cos}90\xb0=0$
