Arrange the vectors additions so that their magnitudes are in the increasing order
a) two vector A→ and B→ are parallel
b) Two vectorsA→ and B→ are anti parallel
c) Two vectorsA→ and B→ making an angle 60°
d) Two vectors A and B→ making 120°.
b, d, c, a
b, c, d, a
a, c, d, b
c, d, a, b
R=A2+B2+2ABcosθ
If θ=0 then R=A+B
If θ=60 then R=A2+B2+2ABcos60==A2+B2+AB
If θ=120 then R=A2+B2+2ABcos120==A2+B2-AB
If θ=180 then R=A-B
