Answer 2

In both conditions the sum of forces will be zero.

Explanation:

• The analytical conditions says that
• If a system is at co-planer and parallel forces are acting on the body.
• The sum of the forces in this system will be zero.
• Similarly, If a system is in parallel then all the forces acting on the system must be in equilibrium.
• Then at that moment the algebric sum of all the parallel forces at any point will be zero.
• Hence the in both conditions the sum of forces will be zero.
