Q)

Find the scalar components and magnitude of the vector joining the points P(x1,y1,z1) and Q(x2,y2,z2).

(A) The scalar components of PQ are (x2−x1),(y2−y1)and(z2−z1),√(x2−x1)2+(y2−y1)2+(z2−z1)2(B) The scalar components of PQ are(x1−x2),(y1−y2)and(z1−z2),(x2−x1)2+(y2−y1)2+(z2−z1)2(C) The scalar components of PQ arex1y1andz1,(x2−x1)2+(y2−y1)2+(z2−z1)2(D) The scalar components of PQ arex2y2andz2,(x2−x1)2+(y2−y1)2+(z2−z1)2
