MCQ
Three forces starts acting simultaneously on a particle moving with velocity $\vec{v}$. These forces are represented in magnitude and direction by the three sides of a triangle $A B C$ (as shown). The particle will now move with velocity
Image
  • $\vec{v}$ remaining unchanged
  • B
    Less than $\vec{v}$
  • C
    Greater than $\vec{v}$
  • D
    $\vec{v}$ in the direction of the largest force $B C$

Answer

Correct option: A.
$\vec{v}$ remaining unchanged
(a) Net force on the particle is zero so the $v$ remains unchanged.
