Given that `A=B=C`. If `vecA+vecB=vecC` then the angle between `vecA and vecC` is `theta_(1)`. If `vecA+vecB+vecC=0` then the and between `vecA and vecC is theta_(2)`. What is the relation between `theta_(1) and theta_(2)?`

Options

A. `theta_(1)=theta_(2)`
B. `theta_(1)=theta_(2)//2`
C. `theta_(1)=2theta_(2)`
D. none of these

Answer
