MathematicsHard202×since 2002Q5796Let u→=i^+j^, v→=i^−j^\overrightarrow u = \widehat i + \widehat j,\,\overrightarrow v = \widehat i - \widehat ju=i+j,v=i−j and w→=i^+2j^+3k^ .\overrightarrow w = \widehat i + 2\widehat j + 3\widehat k\,\,.w=i+2j+3k. If n^\widehat nn is a unit vector such that u→.n^=0\overrightarrow u .\widehat n = 0u.n=0 and v→.n^=0 ,\overrightarrow v .\widehat n = 0\,\,,v.n=0, then ∣w→.n^∣\left| {\overrightarrow w .\widehat n} \right|w.n is equal to :A333B000C111D222Check answerSkip
