PhysicsLaws of MotionJEE Main

When forces F₁, F₂, F₃ are acting on a particle of mass m such that F₂ and F₃ are mutually perpendicular, the particle remains stationary. If the force F₁ is now removed, the acceleration of the particle is

Answer: (A)

Solution

Since F₂ and F₃ are mutually perpendicular, their resultant is √(F₂²+F₃²). For equilibrium this must be equal and
