STANDARD Physics Equilibrium of Forces MCQ Question
Type: MCQ-conceptual-Medium-Class 11
A particle moving with velocity v is acted by three forces shown by the vector triangle PQR. The velocity of the particle will
A
change according to the smallest force QR
B
increase
C
decrease
D
remain constant
Correct Answer
Option D
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.
