Question

If r=2i+3j and F=6i+3k, then find magnitude of work.​

Answer 1

Answer:$Consider the problemlet the vector given are,a=6 i^ −2 j^​ +3 k^ b=2 i^ +3 j^​ −6 k^ c=3 i^ +6 j^​ −2 k^ now magnitude,∣a∣= 6 2 +2 2 +3 2 ​ = 49​ =7Similarly, b=7 and c=7Therefore, the triangle formed by these vectors is Equilateral.$
