NEET Physics Friction and Pulley Systems MCQ Question
A trolley of mass 20 kg is attached to a block of mass 4 kg by a massless string passing over a frictionless pulley as shown in the figure. If the coefficient of kinetic friction between trolley and the surface is 0.02, then the acceleration of the trolley and block system is (Take g = 10 m s⁻²)
1 m s⁻²
2 m s⁻²
5 m s⁻²
5 m s⁻²
Correct Answer
Detailed Explanation
The net force acting on the system is the difference between the gravitational force on the block and the frictional force on the trolley. Using F = ma, the acceleration can be calculated.
