Question

Find the position vectors the following point A(-6,_2,3)B(-4,3,0)C)2,5,-6)​

Answer 1

Answer:

Let the midpoint of PQ be R

Position vector of P=(2−0)i^+(3−0)j^+(4−0)k^

                           OP=2i^+3j^+4k^

 Position vector of Q=(4−0)i^+(1−0)j^+(−2−0)k^

                           OQ=4i^+j^−2k^     

Now,

Position vector of R=2OQ+OP

                           OR=2(4i^+j^−2k^)+(2i^+3j^+4k^) 

                           OR=2(4+
