हिन्दीA particle moving with velocity \( \vec{v} \) is acted by three forces shown by the vector triangle PQR. The velocity of the particle will:
View Answer & Solution
Correct answer · Option A
remain constant
Explanation
Since the three forces form a closed loop in order (triangle PQR), their resultant force is zero. Thus, acceleration is zero and velocity remains constant.
