MCQ
What is direction of vector $\vec{\text{a}}$ if it is multiplied with $-\lambda$:
  • A
    Downwards
  • B
    Upwards
  • C
    Same
  • Opposite

Answer

Correct option: D.
Opposite
If the vector is multiplied with $-\lambda$ then its direction become opposite as the direction in which it was previous may be positive or negative. After it is multiplied with a negative value then its direction becomes exactly opposite to the previous direction.
