Question

State parelleogram law of vectors. Derive an expression for the magnitude and direction of the resultant vector.

Answer 1

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