Find the magnitude of the vector vec(PQ), its scalar components and the component vectors along the co-ordinate axes, if P and Q have the co-ordinates P(1,4,-), Q(2,-2,-1)

Answer»

Solution :`vec(PQ) = (2-1)hati+(-2-4)HATJ+(-1+3)hatk`
= `hati-6hatj+2hatk`
`|vec(PQ)| = sqrt(1+36+4) = sqrt(41)`
Scalar COMPONENTS are 1, -6, 2.
VECTORS components are `hati, -6hatj, 2hatk`
