PhysicsMotion in a PlaneJEE Main

Two forces are such that the sum of their magnitudes is 18 N, and their resultant is perpendicular to the smaller force, with magnitude of the resultant 12 N. The magnitudes of the forces are

Answer: (B)

Solution

Let the smaller force be F₁ and larger F₂, with F₁ + F₂ = 18. Since the resultant R is perpendicular to F₁, by the right-triangle relation (the
