Fven that ` vec A xx vec B= vec B xx vec C = vec 0`. If ` vec A. vec B` and ` vec C` are not null vectors, find the value of ` vec Cxx vec A`.

Explanation

Given, ` vec A xx ve B =vec 0`, it means ` vec A` is parallel of antiparallel to ` vec B . As, vec B xx vec C = vec 0` it means ` vec B` is parallel or antiparallel to ` vec C`. Hence, ` vec A, vec B` amd ` vec C`, are all parallel or antiparallel to each tjer. Therefore, ` vec A` and ` vec C` ar parallel or antiparallel. Hence,
` vec C xx vec A= CA sin 0^2 hat n = vec 0`.
