Question

The angle between A ⃗=^ i +^ j and B ⃗=^ i−^ j is a)45 b) 60 c) 90 d)180​

Answer 1

Answer:

90

Explanation:

Given that, A = i^+ j^

and B = i^ − j^

∵ A⋅ B =0

Since the dot product of the two vectors is zero, it means that the vectors are perpendicular to each other.

Hence, Angle between vectors, A and B is 90 .
