Coordinates of P is (5, 0, 8).
Coordinates of Q is (3, 3, 2).
Position vector of P is given by,
Position vector of Q is given by,
To find unit vector in the direction of PQ, we need to find position vector of PQ.
Position vector of PQ is given by,
We know that, a unit vector in a normed vector space is a vector (often a spatial vector) of length 1.
To find a unit vector with the same direction as a given vector, we divide by the magnitude of the vector.
For finding unit vector, we have the formula:
Thus, unit vector in the direction of PQ is .
