Question

Given that A+B+C =0. Out of three vectors
two are equal in magnitude and magnitude of
third vector in 2 times that of either of two
having equal magnitude. Then angle between
vectors are given by
(1) 90°, 135°, 135°
21 90°, 45°, 45°
(3) 90°, 135°, 45°
(4) 90°, 60°, 30°​

Answer 1

Answer:

2) 90°, 45°,45°

Because when we ,

45°, 45° = 90°

So 90° + 90° = 180°

Answer 2

Explanation:

Given that A+B+C =0. Out of three vectors

two are equal in magnitude and magnitude of

third vector in 2 times that of either of two

having equal magnitude. Then angle between

vectors are given by

(1) 90°, 135°, 135°
