A particle moves rom a point `vecr_1=(2m)veci(3m)vecj` to another point `vecr_2=(3m)veci+(2m)vecj` during which a certain force `vecF(5N)veci+(5N)vecj` acts on it. Fikd the work doen by the force on the particle during the displcement.

Given `vecr_1=2veci+3vecj`
`vecr_2=3veci+2vecj`
so, displacement vector is given by
`vecr=vecr_2-vecr_1` ltbr `=(3veci+2vecj)-(2veci+vecj)`
`=veci-vecj`
Again `vecF=5veci+5vecj`
So, work doe `=vecF.vecS=5xx1+5(-1)=0`
