Three forces $\vec{PQ}$, $\vec{QR}$ and $\vec{RP}$ acts on a body simultaneously. Velocity of the body will
Answer & explanation
Correct answer: option 1
From the given diagram, the forces are forming closed loop in same order.
∴ $\vec{F_{net}}$ = 0
⇒ m$\frac{\vec{dv}}{dt}$ = 0
⇒ $\vec{v}$ = constant.
