Question

Three forces start acting simultaneously on a particle moving with velocity vecv . These forces are represented in magnitude and direction by the three sides of a triangle ABC(as shown). The particle will now move with velocity (A) less than vecv (B) greater than vecv (C) |v| in the direction of the largest force BC (D)  vecv , remaining unchanged.

According to triangle law of vector addition if three vectors addition if three vectors are represented by three sides of a triangle taken in same order, then their resultant is zero. Therefore resultant of the forces acting on the particle is zero, so the particles velocity remains unchanged.
