MCQ
Three forces start acting simultaneously on a particle moving with velocity $\vec{\text{v}.}$ These forces are represented in magnitude and direction by three sides of a triangle taken in the same order. The particle will now move with a velocity.
  • A
    Less then $\vec{\text{v}}$
  • B
    More than $\vec{\text{v}}$
  • C
    $\vec{\text{v}}$ only
✓

Answer

  1. $\vec{\text{v}}$ only.

Explanation:

Resultant of three forces represented completely by three sides of a triangle taken in the same order is zero. Therefore, velocity of particle remains unaffected.
