JEE Main Physics question

Physics Laws of Motion JEE Main

Statement 1: Friction is a self-adjusting force. Statement 2: The magnitude of static friction is always equal to the applied force, and its direction is opposite to that of the applied force.

(A)Assertion is True, Reason is True; Reason is correct explanation for AssertionCorrect
(B)Assertion is True, Reason is True; Reason is not correct explanation for Assertion
(C)Assertion is True, Reason is False
(D)Assertion is False, Reason is True

Answer: (A)

Solution

In this standard context, "friction" refers to static friction (the force preventing relative sliding), which does adjust itself in magnitude and direction to exactly balance the applied
