Step 1

firstly, we find vector v , that is vector PQ, which is equal to (position vector of Q)-(position vector of P)

Step 2

We know that any vector parallel to a given vector is m times that vector , where m is any scalar.

Let vector a is parallel to vector v

Step 3

Since length of vector a is 84 , th...
