JEE Main Physics question

Physics Laws of Motion JEE Main

**Statement I:** The value of dynamic (kinetic) friction is less than the limiting friction. **Statement II:** Once the motion has started, the inertia of rest has been overcome.

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

Answer: (A)

Solution

Kinetic friction is indeed generally smaller than the maximum (limiting) static friction (Statement I true). Once the body starts moving, the initial "sticking"/inertia-of-rest resistance between the surfaces no
