A force of F⃗=3i⃗−5j⃗\vec{F}=3\vec{i}-5\vec{j}F=3i−5j​ is applied continuously on four different objects, causing each object to displace along vector. During which displacement does this force do the largest negative work on the objects?

A) Δr⃗=2i⃗−2j⃗\Delta\vec{r}=2\vec{i}-2\vec{j}Δr=2i−2j​       B) Δr⃗=3i⃗+j⃗\Delta\vec{r}=3\vec{i}+\vec{j}Δr=3i+j​        C) Δr⃗=+4i⃗+3j⃗\Delta\vec{r}=+4\vec{i}+3\vec{j}Δr=+4i+3j​       D) Δr⃗=i⃗+4j⃗\Delta\vec{r}=\vec{i}+4\vec{j}Δr=i+4j​

 Δr⃗=2i⃗−2j⃗\Delta\vec{r}=2\vec{i}-2\vec{j}Δr=2i−2j​      

 Δr⃗=3i⃗+j⃗\Delta\vec{r}=3\vec{i}+\vec{j}Δr=3i+j​       

 Δr⃗=+4i⃗+3j⃗\Delta\vec{r}=+4\vec{i}+3\vec{j}Δr=+4i+3j​     

 Δr⃗=i⃗+4j⃗\Delta\vec{r}=\vec{i}+4\vec{j}Δr=i+4j​
