NEET 2026 Physics Dynamics of a Particle MCQ Question
The magnitude and direction of the acceleration produced in a body of mass 5 kg when two mutually perpendicular forces 8 N and 6 N act on it, are respectively:
20 m s⁻²; tan⁻¹ (4/3) with 8 N force
2 m s⁻²; tan⁻¹ (3/4) with 6 N force
2 m s⁻²; tan⁻¹ (4/3) with 8 N force
2 m s⁻²; tan⁻¹ (3/4) with 8 N force
Correct Answer
Detailed Explanation
The net force F_net = √(6² + 8²) = 10 N. The acceleration a = F_net/m = 10/5 = 2 m/s². The angle θ = tan⁻¹(3/4) from 8 N.
