Laws of Motion Part 1

As shown in the figure, the three forces are represented by the sides of a triangle taken in the same order. So the particle will be in equilibrium under the three forces.
Therefore the resultant force is zero.

Therefore acceleration will be zero.
Hence the particle velocity remains unchanged.
