FIND A UNIT VECTOR IN THE DIRECTION FROM POINT P(1,-1,2) TO POINT Q(-1,1,1)

Question

Arun · Answer

Dear Ganesh first find out the vector from P to Q vector PQ = ( – 1, 1, 1) – (1, – 1, 2) = – 2i + 2j – k hence unit vector = – 2i + 2j – k / (sqrt(4 + 4 + 1)) = (– 2i + 2j – k )/ 3 Regards Arun

Rajdeep · Answer

Hello Ganesh, Given points are: Initial Point: P(1, -1, 2) Final Point: Q(-1, 1, 1) Hence, unit vector in the direction P->Q is (-1-1) i + [1-(-1)] j + [1-2]k = -2i + 2j – k Thanks!
