A= F ;

B= F

R = F
so anglex = we have to calculate...

R = √A² + B² + 2ABcosx

F = √F² + F² + 2FxFcosx

= F√2(1+cosx)

1=2(1+cosx)

cosx= -1/2 = cos 120°

so answer is 120°

Answer 2

Hey Mate,

These are inclined at angle 120°

because these are considered as vectors and the pure resulrant vector are only inclined at this angle so as to cancel each other

further,

➡R = √A² + B² + 2ABcosx

➡F = √F² + F² + 2FxFcosx

➡= F√2(1+cosx)

➡1=2(1+cosx)

➡cosx= -1/2

➡= cos 120°
