Three vectors are all in the same plane,they have equal magnitudes and make 120 $\circ$ angles with each other.We can say that
A)the magnitude of their resultant is three times the magnitude of each component vector.
B)the magnitude of their resultant is more than three times the magnitude of each component vector.
C)the magnitude of their resultant is one-third the magnitude of the component vectors.
D)the magnitude of their resultant is zero.
E)the magnitude of their resultant is equal to the magnitude of the component vectors.

Question

Quizplus · Accepted Answer

When three vectors of equal magnitude are arranged in a plane making 120° angles with each other, they form an equilateral triangle when their tails are placed at the same point. The resultant vector, which is the sum of these three vectors, is zero because they cancel each other out due to their symmetrical arrangement.
