Question

Statement 1: While drawing a line on a paper, friction force acts on paper in the same direction along which line is drawn on the paper.
Statement 2: Friction always opposes motion.

• A. Both statements 1 and 2 are true and statement 2 is the correct explanation of statement 1
• B. Both statements 1 and 2 are true but statement 2 is the not correct explanation of statement 1
• C. Statements 1 is true and statement 2 is false
• D. Both statements 1 and 2 are false

Answer 1

The correct option is C Statements 1 is true and statement 2 is false

When we draw a line left to right then the tip of pen move left to right also but $\text{the friction always oppose relative motion so it will oppose the tip to move left to right}$

but it can't stop the tip as we force the tip but the $\text{the ink get stuck on the paper.}$

As the paper apply a force right to left to oppose the rightward motion of tip so the tip will apply a friction

$\text{from left to right on the paper.}$

When we climb over a rope then it is the friction which $support$ our motion against slipping.

so option C is correct.
