Statement 1 It is easier to pull a heavy object than to push it on a level ground.
and Statement 2 The magnitude of frictional force depends on the nature of the two surfaces in contact.
- A Statement 1 is true, Statement 2 is true, Statement 2 is a correct explanation for Statement 1.
- B Statement 1 is true, Statement 2 is true, Statement 2 is not a correct explanation for Statement 1.
- C Statement 1 is true, Statement 2 is false.
- D Statement 1 is false, Statement 2 is true
Answer & Solution
Correct Answer
(B) Statement 1 is true, Statement 2 is true, Statement 2 is not a correct explanation for Statement 1.
Step-by-step Solution
Detailed explanation
Both statements are correct. But statement-2, does not explain correctly, statement- 1 . Correct explanation is : "There is increase in nomal reaction when the object is pushed and there is decrease in normal reaction when the object is pulled (but strictly not horizontally).
