Question

Given that A and B are greater than 1. The magnitude of vector (A x B) cannot be 

1. Equal to AB 
2. Less than AB 
3. More than AB 
4. Equal to A/B

Answer 1

Correct Answer : 3. More than AB

Explanation :

vector (A x B) = AB sin θ

∵ sin θ ≤  1

|vector (A x B)|  ≤ AB

|vector (A x B)| cannot be greater than AB 

|vector (A x B)|  ≤ AB
