Let P = I P - P , be any vector. Another vector Q which is perpendicular to P is

Options

  1. A( I Q + j Q )
  2. B( I Q + j Q )
  3. C( I Q - j Q )
  4. D( l P + j P )

Correct answer

B. ( I Q + j Q )

Step-by-step solution

P =P i -P j also, Q =Q i +Q j P . Q =(P i -P j ) (Q i +Qsin j )=P Q -P - Q =0
