Question

69. IfA=B then the angle between (A + B) and (A x B) is
​

Answer 1

Answer:

Correct option is

A

45o

Given  :      A.B=A×B             

Taking mod on both sides,      ∣A.B∣=∣A×B∣ 

OR      ∣A∣∣B∣cosθ=∣A∣∣B∣sinθ 

OR     sinθ=cosθ

OR     tanθ=1                   

⟹θ=45o

Explanation:

if it's correct then let me know

Answer 2
