Question

A parallelogram law helps to find the magnitude and direction of the resultant of two forces: (a)State the law. (b)If the magnitude of two vectors and their resultant are the same, what is the angle between the two vectors? (c)Determine the value of (A-B) x (A+B).​

Answer 1

Answer:

When the magnitude of Resultant and the value of two vector is equal then the angle between them is : Cos 120° or Cos -1/2.

pls mark me as a brainiest
