Question

()) if a, b and a x b are three unit vectors, find the angle
between the vectors a and b.​

Answer 1

Answer:

90° or π/2

Step-by-step explanation:

given.....

| a x b | = 1 ; |a| = 1 ; |b| = 1

now....since

| a x b | = |a| |b| sin @

1 = 1 × 1 × sin @

sin @ = 1

but....

sin 90° = 1

hence...

@ = 90°
