Question

Assertion (A): Skiers use short flat skies to slide over the snow.
Reason (R): They can slide easily on the snow because larger the area of contact, the lesser will be the pressure on the snow.

• A. A is correct and R is the correct reason for A.
• B. A is correct but R is not the correct reason for A.
• C. A is incorrect but R is correct.
• D. Both A and R is incorrect.

Answer 1

The correct option is C

A is incorrect but R is correct.

Skiers use long flat skies to slide over the snow. Long skies are needed so that when a skier goes at a great speed, the snow at a meter ahead of the person gets softened for skiing over that by the time the skier reaches that point. This is because larger the area of cross-section, the lesser is the pressure on the snow. This helps the skier to slide comfortably without sinking in the snow. ​
