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` |
