Question

Which of the following sets of three concurrent forces acting in a plane can possibly be in equilibrium?

Accepted Answer

Three forces can be in equilibrium if the sum of the magnitudes of any two forces is greater than or equal to the magnitude of the third force. Checking the options, for $2	ext{ N}, 3	ext{ N}, 5	ext{ N}$, $2 + 3 = 5$, which satisfies the triangle inequality condition for equilibrium.
