STANDARD Physics Equilibrium of Forces MCQ Question
A body is moving under the action of two forces F₁ = 2î - 5ĵ ; F₂ = 3î - 4ĵ. Its velocity will become uniform under a third force F₃ given by
5î - ĵ
-5î - ĵ
5î + ĵ
-5î + 9ĵ
Correct Answer
Detailed Explanation
For uniform velocity, acceleration is zero. Hence resultant force will be zero. ∴ F₁ + F₂ + F₃ = 0 (2î - 5ĵ) + (3î - 4ĵ) + F₃ = 0 or F₃ = (-5î + 9ĵ)
