MCQ

Given that; $A = B = C$. If $\vec A + \vec B = \vec C,$ then the angle between $\vec A$ and $\vec C$ is $\theta _1$. If $\vec A + \vec B+ \vec C = 0,$ then the angle between $\vec A$ and $\vec C$ is $\theta _2$. What is the relation between $\theta _1$ and $\theta _2$ ?

A
$\theta _1=\theta _2$
✓
$\theta _1=\theta _2/2$
C
$\theta _1=2\theta _2$
D
None of these

✓

Answer
