Explain solution RD sharma class 12 chapter 22 algebra of vectors exercise 22.5, question 12 sub question 1

Answers (1)

: The components of \vec{P} along x axis is a vector of magnitude 3 along the positive direction of x axis

The component of \vec{P} along y axis is a vector of magnitude 2 along the positive direction of Y axis

3\hat{i},2\hat{j}

Hint: position vector of point (x, y) is given by x\hat{i}+y\hat{j} where \hat{i} and \hat{j} are the unit vector in x and y direction

Given: P(3,2)

Solution:

As we know, position vector of a point (x, y) is given by x\hat{i}+y\hat{j}

Then,

Position vector of a point (3, 2) is \vec{p}=3\hat{i}+2\hat{j}

The components of \vec{P}along x axis is a vector of magnitude 3 along the positive direction of x axis

The component of \vec{P} along y axis is a vector of magnitude 2 along the positive direction of Y axis
