(a) 3 î + B - 4 ĵ = 1 ĵ
For the three vectors shown in (Figure 1), A + B + C = 1 ĵ. (Not necessarily to scale.)
(a) Write B in component form. Express your answer in terms of the unit vectors î and ĵ.
(b) What is the magnitude of B ? Express your answer using two significant figures.
(c) What is the direction angle of B , measured clockwise from the negative x axis? Express your answer using two significant figures.
