MCQ
જો $\vec a = 2\hat i + \hat j + \hat k,\vec b = \hat i + 2\vec j + 2\vec k,\vec c = \vec i + \vec j + 2\hat k$ અને $\left( {1 + \alpha } \right)\hat i + \beta \left( {1 + \alpha } \right)\hat j + \gamma \left( {1 + \alpha } \right)\left( {1 + \beta } \right)\hat k = \hat a \times \left( {\vec b \times \vec c} \right)$ હોય તો $\alpha ,\beta ,\gamma $ ની કિમત અનુક્રમે ......... થાય
- A$ - 2, - 4, - \frac{2}{3}$
- B$ 2, - 4, \frac{2}{3}$
- C$ - 2, 4, \frac{2}{3}$
- D$ 2, 4, - \frac{2}{3}$
