Question

If a vector + b vector is equal to our result and where a is equal to R and the angle between vector and our vector is 120 degree find the ratio of B/a​

Answer 1

Answer:

 If the angle between two vectors A and B is 120^(@), then its ... C=√A2+B2+2ABcos120∘ ... Two equal vectors have a resultant equal to either of them, ...
