If there are coplanar forces acting on a body to keep it in equilibrium, then these forces are:
Correct answer: A. Concurrent
- A. Concurrent
- B. Non-concurrent
- C. Parallel
- D. Anti-parallel
Explanation
"A group of forces acting on an object is called a coplanar system of forces if the line of action of all the forces lies in the same plane."A coplanar force system is considered a concurrent coplanar force system if the line of action of all the forces passes through the same point. For the given case of three forces, when three or more coplanar forces are acting at a point and the vector diagram closes, there is no resultant. The forces acting at the point are in equilibrium. When three or more coplanar forces are acting at a point and the vector diagram closes, there is no resultant. The forces acting at the point are in equilibrium.

About Addition of Vectors
Vector addition combines directed quantities using the head-to-tail, parallelogram and component methods. Work includes finding the resultant magnitude and direction for two or more vectors, resolving vectors into perpendicular components, and distinguishing vector addition from scalar addition, where direction has no role.
