Three forces start acting simultaneously on a particle , moving with velocity, `vec(v)` . 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. `vec(v)`, remaining unchanged
B. less than `vec(v)`
C. greater than
D. `|vec(v)|` in the direction of the largest force BC.

Answer

A

Explanation

As the forces are represented by the sides of a triangle taken in order their resultant is zero. Hence they produce no change in velocity.
