A particle moving with velocity V is acted by three forces shown by the vector triangle PQR. The velocity of the particle will

  1. increase
  2. decrease
  3. remain constant
  4. change according to the smallest force QR

Solution

We know that sum of vector in a loop arranged in tip-to tail manner is zero.

So, here the sum of forces arranged in tip-to-tail manner is zero.

Fnet=0
Since, the sum of forces is zero.acceleration will be zero and Velocity will remain constant.
