ધારો કે $\vec{a} = 3\hat{i} + 2\hat{j} + x\hat{k}$ અને $\vec{b} = \hat{i} - \hat{j} + \hat{k}$,કોઈ વાસ્તવિક $x$ માટે. તો $|\vec{a} \times \vec{b}| = r$ શક્ય છે જો

  • A
    $r \geq 5\sqrt{\frac{3}{2}}$
  • B
    $3\sqrt{\frac{3}{2}} < r < 5\sqrt{\frac{3}{2}}$
  • C
    $\sqrt{\frac{3}{2}} < r \leq 3\sqrt{\frac{3}{2}}$
  • D
    $0 < r \leq \sqrt{\frac{3}{2}}$
