Question

A vector has component along the $x$-axis equal to $25\text{unit}$ and along the $y$-axis equal to $60\text{unit}$. Then the position vector will be

• A. $\overrightarrow{p}=25\hat{i}+60\hat{j}$
• B. $\overrightarrow{p}=25\hat{j}+60\hat{k}$
• C. $\overrightarrow{p}=25\hat{i}+60\hat{k}$
• D. $\overrightarrow{p}=25\hat{j}+60\hat{i}$

Answer 1

The correct option is A $\overrightarrow{p}=25\hat{i}+60\hat{j}$

$25$ unit in $x$ means $25\hat{i}$ and $60$ unit in $y$ means $60\hat{j}$
So the position vector will be $\overrightarrow{p}=25\hat{i}+60\hat{j}$
