NEET 2026 Physics question
A box of mass 15 kg is kept on the floor of a stationary trolley. The coefficient of static friction between the box and the trolley is 0.12. Keeping the box in stationary state over the trolley, the maximum acceleration with which the trolley can be moved horizontally in m s is: ()
Answer: (4)
Solution
The box accelerates along with the trolley only because of static friction, . Static friction has a maximum . The box stays at rest relative to the
