Vector A has a magnitude of 5 units and is directed north vector b has a magnitude of 4 units and is directed west . by constructing vector diagrams find the magnitudes and direction of A+b and A-B?
magnitude A=5magnitude B=4magnitude of A+B= sqrt(A2+B2+2ABcos(teeta)) (here teete=90)magnitude of A-B= sqrt(A2+B2-2ABcos(teeta)) (here teete=90)magnitude of A+B=magnitude of A-Bthen A+B=sqrt(25+16)=root(41)there fore magnitude of A+B=magnitude of A-B= root(41) THANK YOU
