Question

Define position vector and write the position vector of point $straight P left right arrow left parenthesis straight x comma space straight y comma space straight z right parenthesis$ .

Solution

A vector drawn from reference point to a given point is known as position vector of that point.
Position vector of point P is $space OP with rightwards arrow on top.$
Here, $straight P left right arrow left parenthesis straight x comma space straight y comma space straight z right parenthesis$
Therefore,
$OP with rightwards arrow on top space equals space left parenthesis straight x minus 0 right parenthesis straight i with hat on top space plus space left parenthesis straight y minus 0 right parenthesis straight j with hat on top plus left parenthesis straight z minus 0 right parenthesis straight k with hat on top$
$space equals straight x straight i with hat on top plus straight y straight j with hat on top plus straight z straight k with hat on top$
