Unit Vector Question
Asked by RACHIT_MAHAAN | 24 Aug, 2010, 07:45: AM
Expert Answer
Since parallel unit vectors have the same direction, the required unit vector is the unit vector in the direction of resultant.
The resultant,
R = A + B
= i + 4j - 2k + 3i - 5j + k
= 4i - j - k
The unit vector = (4i - j - k)/√(42 + 12 + 12) = (4i - j - k)/√(18)
