Let ( u ) and ( v ) be two non-zero vectors. Then the magnitude of the cross product ( u v ) is always

Options

  1. A( < |u||v| )
  2. B(=|u||v| )
  3. C(>|u||v| )
  4. D(=0 )

Correct answer

A. ( < |u||v| )

Step-by-step solution

The cross product of (u ) and (v ) non-zero vectors is ( u v =| u | v | n ), if angle between them is ( ). So, ( |u v|=|u||v|| | ) ( |u v| |u||v| | | 1 )
