RE-NEET 2024 Physics Inclined Planes MCQ Question
A box of mass 5 kg is pulled by a cord, up along a frictionless plane inclined at 30° with the horizontal. The tension in the cord is 30 N. The acceleration of the box is (Take g = 10 m s⁻²)
2 m s⁻²
Zero
0.1 m s⁻²
1 m s⁻²
Correct Answer
Detailed Explanation
The net force along the incline is T - mg sin(θ). Using F = ma, the acceleration a = (T - mg sin(θ))/m = (30 - 5100.5)/5 = 1 m/s².
