A particle moving with velocity V → is acted by three forces shown by the vector triangle P Q R . The velocity of the particle will

Options

  1. Aincrease
  2. Bdecrease
  3. Cremain constant
  4. Dchange according to the smallest force Q R →

Correct answer

C. remain constant

Step-by-step 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. F net → = 0 Since, the sum of forces is zero.acceleration will be zero and Velocity will remain constant.
