Question

When a body is subjected to two forces, the body will be equilibrium if the two forces are:

• A. collinear, equal and act in the same direction
• B. collinear, unequal and opposite
• C. non collinear, equal and opposite
• D. collinear, equal and opposite

Answer 1

Answer:

D. collinear, equal and opposite

When a body is in equilibrium, it means there is no net force acting on it, and it is either at rest or moving at a constant velocity. For this to happen, the forces acting on the body must cancel each other out. This can be achieved when the two forces are collinear (meaning they have the same line of action), equal in magnitude, and opposite in direction. In this scenario, the forces balance each other, resulting in a state of equilibrium for the body.
