1.If the vectors a⃗=i^−j^+2k^\vec{a} = \hat{i} - \hat{j} + 2\hat{k}a=i^−j^+2k^, b⃗=2i^+4j^+k^\vec{b} = 2\hat{i} + 4\hat{j} + \hat{k}b=2i^+4j^+k^ and c⃗=λi^+j^+μk^\vec{c} = \lambda\hat{i} + \hat{j} + \mu\hat{k}c=λi^+j^+μk^ are mutually orthogonal, then (λ,μ)=(\lambda, \mu) =(λ,μ)=a.(2,−3)(2, -3)(2,−3)b.(−2,3)(-2, 3)(−2,3)c.(3,−2)(3, -2)(3,−2)d.(−3,2)(-3, 2)(−3,2)Login to continueOnly logged in users canattempt or see the solution.
