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

Options

  1. Aincrease
  2. Bdecrease
  3. Cremain constant
  4. Dchange according to the smallest force QR→\overset{\to}{QR}

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.

Fnet→=0\overset{\to}{{F}_{net}} = 0
Since, the sum of forces is zero.acceleration will be zero and Velocity will remain constant.
