Given that `P=Q=R`. If `vec(P)+vec(Q)=vec(R)` then the angle between `vec(P)` and `vec(R)` is `theta_(1)`. If `vec(P)+vec(Q)+vec(R)=vec(0)` then the angle between `vec(P)` and `vec(R)` is `theta_(2)`. The relation between `theta_(1)` and `theta_(2)` is :-

A

`theta_(1) = theta_(2)`

B

`theta_(1) = (theta_(2))/(2)`

C

`theta_(1) = 2theta_(2)`

D

None of the above
