JEE Main Physics question

Physics Laws of Motion JEE Main

**Statement I:** Friction is a self adjusting force. **Statement II:** Friction does not depend upon the area of the body.

(A)Statement I is true, Statement II is true; Statement II is a correct explanation for Statement I
(B)Statement I is true, Statement II is true; Statement II is not a correct explanation for Statement ICorrect
(C)Statement I is true, Statement II is false
(D)Statement I is false, Statement II is true

Answer: (B)

Solution

Static friction genuinely adjusts itself in magnitude and direction to exactly balance the applied force up to its limiting value — this is precisely why it is called "self-adjusting" — so Statement I is true. Friction is also independent of the apparent area of contact (it depends
