NEET Physics Friction MCQ Question
Consider a diagram showing a block sliding down a rough inclined plane. Label the forces acting on the block, including friction. Which arrow correctly represents the direction of the frictional force?
Up the incline, opposite to the direction of motion.
Down the incline, in the direction of motion.
Perpendicular to the incline, away from the surface.
Parallel to the incline, in the same direction as motion.
Correct Answer
Detailed Explanation
Frictional force opposes the relative motion between surfaces in contact, acting up the incline when the block slides down.
