A piece of paper and a coin both having the same mass are dropped from the 10th floor of building. The piece of paper would take more time to reach the ground because
  • a)
    gravitational pull on the paper is less than the coin.
  • b)
    buoyant force on the piece of paper is more than that on the coin.
  • c)
    buoyant force on the coin is more and acts in the downward direction.
  • d)
    the piece of paper takes a longer path to reach the ground.
Correct answer is option 'B'. Can you explain this answer?

The piece of paper would take more time to reach the ground than a coin because buoyant force on the piece of paper is more than that on the coin. If piece of paper and coin having the same mass are droped from the same height in vacuum then both will take the same time to reach the ground.

Explanation:

Buoyant Force:
- The piece of paper would take more time to reach the ground because the buoyant force acting on the paper is more than that on the coin.
- Buoyant force is the force exerted by a fluid (in this case, air) that opposes the weight of an object immersed in it.
- Since the piece of paper has a larger surface area compared to the coin, it experiences a greater buoyant force due to air resistance.
- This buoyant force slows down the descent of the paper, causing it to take more time to reach the ground compared to the coin.

Gravitational Pull:
- The gravitational pull on both the paper and the coin is the same since they have the same mass.
- Gravity acts equally on both objects, pulling them towards the ground with the same acceleration.

Path to Reach the Ground:
- The piece of paper does not take a longer path to reach the ground compared to the coin.
- Both the paper and the coin are dropped from the same height (10th floor), so they follow the same vertical path towards the ground.

Conclusion:
- In conclusion, the piece of paper takes more time to reach the ground because the buoyant force acting on the paper is greater than that on the coin, slowing down its descent due to air resistance.
