Question

State parallelogram law of addition of vectors?. Derive an expression for the magnitude and

direction of the resultant vector using parallelogram law..​

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.
