Answer to Question #56258 in Mechanics | Relativity for adeshina

Question

10 given two vectors

a⃗ =4i^−3j^+2k^

,

b⃗ =i^+2j^−k^

, calculate

a⃗ ×b⃗

2^i−6j^−5k^

−i^+6j^+5k^

−i^−6j^+5k^

−2^i−6j^+5k^

11 given the vectors

a⃗ =i^−2j^+3k^

,

b⃗ =2i^+j^−k^

,

c⃗ =3i^−2j^+3k^

calculate

a⃗ ⋅(b⃗ ×c⃗ )
