Question

Choose the correct statement:

Statement I: Rubbing a fabric together or using a brush applies friction, which helps in loosening and removing dirt particles from the fabric’s surface.

Statement II: Using excessive friction while cleaning delicate fabrics is beneficial, as it ensures all dirt is thoroughly removed without causing any damage.

पर्याय

• Statement I is true, and Statement II is false.

• Statement I is false, and Statement II is true.

• Both Statements I and II are true.

• Both Statements I and II are false.

Answer 1

Statement I is true, and Statement II is false.

Explanation:

Statement I is true because rubbing or brushing creates mechanical friction that physically loosens and dislodges dirt particles from fabric surfaces. Statement II is false because applying excessive friction or scrubbing on delicate fabrics like silk or wool is highly damaging. Rough friction can break, tear, or distort delicate fibres, which is why these materials require a gentle “kneading and squeezing” washing method with minimal friction.
