JEE Main Physics question

Physics Laws of Motion JEE Main

**Statement I:** On a rainy day, it is difficult to drive a car or bus at high speed. **Statement II:** The value of coefficient of friction is lowered due to wetting of the surface.

(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
