JEE Main Physics question

Physics Laws of Motion JEE Main

**Statement I:** Angle of repose is equal to angle of limiting friction. **Statement II:** When the body is just at the point of motion, the force of friction in this stage is called limiting friction.

(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

Both statements are true facts about friction: the angle of repose indeed equals the angle of limiting friction (Statement I), and limiting friction is indeed defined as the friction at the verge of sliding (Statement II). However, Statement II is merely a definition
