A) \[\vec{r}.(7\hat{i}+2\hat{j}+4\hat{k})=54\]
B) \[\vec{r}.(5\hat{i}+4\hat{j}+3\hat{k})=57\]
C) \[\vec{r}.(3\hat{i}+4\hat{j}+5\hat{k})=49\]
D) \[\vec{r}.(4\hat{i}+3\hat{j}+5\hat{k})=50\]
Correct Answer: D
Solution :
\[\therefore \] Equation of plane is \[4(x-4)+3(y-3)\,+5(z-5)=0\]\[\Rightarrow \,\vec{r}.(4\hat{i}+3\hat{j}+5\hat{k})=50\]You need to login to perform this action.
