Question
Three forces start acting simultaneously on a particle moving with velocity 
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
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 Options
A.less than
B.greater than
C.|v| in the direction of the largest force BC
D.
, remaining unchanged.
, remaining unchanged.Solution
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.
