Answers (1)

Answer:

x + y + z = 2 is the required Cartesian product

Hint:

Use vector product

Given:

$\vec{r}.\left ( \hat{i}+\hat{j}+\hat{k} \right )=2$

Solution:

We have,

$\begin{aligned} &\vec{r}.\left ( \hat{i}+\hat{j}+\hat{k} \right )=2\\ &\Rightarrow (x\hat{i}+y\hat{j}+z\hat{k}).\left ( \hat{i}+\hat{j}+2 \right )=2\\ &\Rightarrow x+y+z=2 \end{aligned}$
