Mathematics · JEE Main · NTA Exams — Three Dimensional Geometry
If the vector \(\overrightarrow{\mathrm{b}}\) is collinear with the vector \(\vec{a}=(2 \sqrt{2},-1,4) \&|\vec{b}|=10\), then
- \(\overrightarrow{\mathrm{a}} \pm \overrightarrow{\mathrm{b}}=0\)
- \(\vec{a} \pm 2 \vec{b}=0\)
- \(2 \vec{a} \pm \vec{b}=0\)
- none
Answer
(C) 2 a b =0
