A point charge \[50\mu C\] is located in the x-y plane at a point whose position vector is \[\vec{r}=\left( 2\hat{i}+3\hat{j} \right)m.\]Then electric field at the point whose position vector is \[\vec{r}=\left( 8\hat{i}-5\hat{j} \right)m.\](in vector form) will be

• A. \[90\left( -3\hat{i}+4\hat{j} \right)V/m\]\[\]           
• B. \[900\left( 3\hat{i}-4\hat{j} \right)V/m\]
• C. \[90\left( 3\hat{i}-4\hat{j} \right)V/m\]     
• D. (d)\[900\left( -3\hat{i}+4\hat{j} \right)V/m\]
