STANDARD Physics Equilibrium of Forces MCQ Question
A particle moving with velocity v is acted by three forces shown by the vector triangle PQR. The velocity of the particle will
change according to the smallest force QR
increase
decrease
remain constant
Correct Answer
Detailed Explanation
As per triangle law, F₁ + F₂ + F₃ = 0 i.e., net force on the particle is zero. So, acceleration is also zero. Hence velocity of the particle will remain constant.
