\mathbf{a}=\hat{\mathbf{i}}+\hat{\mathbf{j}}+\hat{\mathbf{k}}, \mathbf{b}=\hat{\mathbf{i}}+\hat{\mathbf{j}}, \mathbf{c}=\hat{\mathbf{i}}

and

(\mathbf{a} \times \mathbf{b}) \times \mathbf{c}=\lambda \mathbf{a}+\mu \mathrm{b}

, then

\lambda+\mu

is equal to

View answer and explanation

Correct option: A

Option A (0) is correct because after calculating the triple product and comparing it to the given equation, we find that λ + μ = 0.
