Solve the following :


A particle moves from a point $r=(2 \mathrm{~m})^{\hat{\imath}}+(3 \mathrm{~m})^{\hat{\jmath}}$ to another point $r_{2}=(3 \mathrm{~m})^{\hat{\imath}}+(2 \mathrm{~m})^{\hat{\jmath}}$ during which a certain force $F=(5 \mathrm{~N})^{\hat{l}}+(5 \mathrm{~N})^{\hat{J}}$ acts on it. Find the work done by the force on the particle during the displacement.




$r=\hat{\imath}_{-} \hat{\jmath}$

Work done $\mathrm{W}=\mathrm{F} \times \mathrm{r}$

$W=\left(5^{\hat{\imath}}+5^{\hat{\jmath}}\right) \times\left({ }^{\hat{\imath}}-\hat{\jmath}\right)$
