NEET Physics Friction MCQ Question
Consider a diagram showing a block of mass m at rest on a horizontal surface with an external force applied. The diagram shows the gravitational force mg acting downward, the normal force N acting upward, and a horizontal applied force F. Which of the following correctly describes the role of static friction in this scenario?
Static friction prevents the block from moving by balancing the applied force F up to a maximum value μsN.
Static friction acts vertically to counterbalance the gravitational force mg.
Static friction is always equal to the applied force F, regardless of its magnitude.
Static friction generates a net force that accelerates the block horizontally.
Correct Answer
Detailed Explanation
Static friction balances the applied force F up to its maximum limit, which is given by μsN, as per the static friction law f s ≤ μs N.
