Q.
A particle moving with velocity $\overrightarrow{v}$ is acted by three forces shown by the vector triangle PQR. The velocity of the particle will:
Solution:
As forces are forming closed loop in same order
SO, $\vec{F}_{net} = 0$
$\Rightarrow \; m \frac{d \vec{V}}{dt} = 0$
$\Rightarrow \; \vec{v}$ = constant
