Question

A point $P$ having the coordinate $(2,3)$. Find the position vector of $P$ ?

• A. $\overrightarrow{P}=2\hat{i}+3\hat{ȷ}$
• B. $\overrightarrow{P}=3\hat{i}+3\hat{ȷ}$
• C. $\overrightarrow{P}=2\hat{i}+2\hat{ȷ}$
• D. $\overrightarrow{P}=3\hat{i}+2\hat{ȷ}$

Answer 1

The correct option is A $\overrightarrow{P}=2\hat{i}+3\hat{ȷ}$

Let $\hat{ı}$, $\hat{ȷ}$ are the unit vector in $x$ and $y$ direction respectively.
So, position vector of point $P$ become $\overrightarrow{P}=2\hat{i}+3\hat{ȷ}$
