JEE Main Physics question
When the angle of inclination of an inclined plane is , an object slides down with uniform velocity. If the same object is pushed up the same inclined plane with an initial velocity , it goes up the plane and stops after a certain distance. Thereafter the body
Answer: (D)
Solution
Sliding down at uniform (constant) velocity means , i.e. exactly — the object is on the verge of sliding, with friction force exactly balancing gravity's component for constant
