Question
Four forces are acting on a body. If the body doesn't change its position or shape, the forces:
✓

Answer

  1. Must add up to zero when taken as vectors
Explanation:
As the body does not change its position or shape, it implies that the net external force acting on the body must be equal to zero since the body is in equilibrium or at rest.
Thus the vector sum of the four forces acting on the body must be zero.
