Question:

A particle moving with velocity V is acted by three forces shown by the vector triangle PQR. The velocity of the particle will :

Options:

Change according to the smallest force QR

Increase

Decrease

Remains constant

Remains constant

Explanation:

As forces are forming closed loop in same order,

Fnet = 0

m\(\frac{dv}{dt}\) = 0

v = constant
