IF the magnitudes of a,b, and a+b are respectively 3,4 and 5 then the magnitude of (a-b) is

The magnitude of x and y components of vec(A) are 7 and 6 respectively . Also , the magnitudes of x and y components of vec(A)+vec(B) are 11 and 9 respectively . Calculate the magnitude of vector vec(B)

The magnitude of x and y components of vec(A) are 7 and 6 respectively . Also , the magnitudes of x and y components of vec(A)+vec(B) are 11 and 9 respectively . Calculate the magnitude of vector vec(B)

When two vectors vecA and vecB of magnitudes a and b respectively are added, the magnitude of resultant vector is always

If vec(A) = vec(B) + vec( C) and the magnitude of A, B and C are 5, 4 and 3 units respectively the angle between vec(A) and vec(B) is:
