Three vectors have equal magnitudes and make 120° with each other. We can say that
A) the magnitude of the resultant is one-third the magnitude of the component vectors.
B) the magnitude of the resultant is three times the magnitude of the component vectors.
C) the magnitude of the resultant is more than three times the magnitude of each component vector.
D) the resultant is zero.
E) the magnitude of the resultant is equal to the magnitude of the component vectors.
