Answer:
A vector = 2cm
B vector = 3cm
Magnitude of resultant vector = R =
=
=
direction of resultant vector = tanα = A\B
= 2/3
= 0.66
α = 33.5 (tan33.5 = 0.66)
A vector = 2(2)cm = 4cm
B vector = 3cm
Magnitude of resultant vector =
=
=
= 5
direction of resultant vector = tanα = A/B
= 4/3
= 1.33
α = 53 ( tan53 = 1.33)
