Three forces start acting simultaneously on a particle moving with velocity, v . These forces are represented in magnitude and direction by the three sides of a triangle ABC . The particle will now move with velocity

Options

  1. Aless than v
  2. Bgreater than v
  3. C| v | in the direction of the largest force BC
  4. Dv , remaining unchanged

Correct answer

D. v , remaining unchanged

Step-by-step solution

According to triangle law of forces, the resultant force is zero. In presence of zero external force, there is no change in velocity
