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,-2), Q(-5,-6) |
|
Answer» Solution :`vec(PQ) = (-5+1)HATI+(-6+2)HATJ = -4hati-4hatj` THEREFORE `|vec(PQ)| = SQRT((4)^2+(4)^2 = 4sqrt2 Scalar components are -4, -4, and vector components are -4, -4 and vector components are -4i, -4J. |
