Question

a)
State parallelogram law of
vectors. Derive an
expression for rhe
magnitude and direction of the
resultant vector.
​

Answer 1

Answer:

The addition of two vector A and vector B is resultant vector R And R = A2 + B2+ 2AB CosΘ1/2And tan β = B SinΘ/ A + B CosΘ Where Θ is the angle between vector A and vector B And β is the angle which vector R makes with the direction of vector A. State triangle law of vectors addition.
