Question

The position vector of the point P and Q in space with respect to the origion and vector r1 and vector r2 if vector r1-3i cap+5j cap-k cap and vector r2=4i- cap 5j cap +3i cap determine PQ vector and its magnitude
​

Answer 1

Answer:

Since

OP ∣=∣ OQ

∣= 14

,ΔOPQ is isosceles.

Hence, the internal bisector OM is perpendicular to PQ and M is the midpoint of P and Q.

∴ OM =2+1

OP+ OO

=2ij −2 k
