the resultant of two vector
A and B pependicular to vector A and its magnitude is equalto half the magnitude of vector b what is the angle between them . How?

Va = F1.
Vb = 2F1.
tanA = Y/X = 2F1/F1 = 2.
A = 63.4 Deg. = Angle between resultant
and Va.
90  63.4 = 26.6 Deg. = Angle between
resultant and Vb.
NOTE: Va is parallel to the xaxis and
Vb is parallel to the yaxis.
