Answer 1

BOTH STATEMENTS ARE TRUE AND 2 IS CORRECT EXPLANATION FOR STATEMENT 1

Answer 2

Let us consider both statements one-by-one.

Assertion : When a person walks on a rough surface, the frictional force exerted by the surface on the person is opposite to the direction of motion.

• This statement is true. When a person walks on a rough surface they push the surface with their feet in the direction in which they want to move. Conversely the surface pulls the person back against the direction in which they are walking.

Reason: Friction always acts opposite to the direction of motion.

• This statement is true. Friction acts in the direction opposite to apparent movement, thereby resisting it.

As you can see from the separate explanations of assertion and reason, the Reason explains the Assertion.

Hence, the correct option is (A) Both statements 1 and 2 are true and statement 2 is the correct explanation of statement 1.
