Direction: Read the following paragraph and choose the correct option...
The acceleration of the object equals the gravitational acceleration. The mass, size, and shape of the object are not a factor in describing the motion of the object. So all objects, regardless of size or shape or weight, free fall with the same acceleration. In a vacuum, a beach ball falls at the same rate as an airliner. Knowing the acceleration, we can determine the velocity and location of any free falling object at any time.

Explanation:
Introduction:
The question asks about the outcome when a coin and a piece of paper are dropped simultaneously from the same height in a vacuum. To answer this, we need to understand the concept of air resistance and its effect on objects falling through the atmosphere.
Understanding Air Resistance:
- Air resistance is the force that opposes the motion of objects through the air.
- When an object falls through the atmosphere, it experiences air resistance, which slows down its descent.
- The amount of air resistance depends on the shape, size, and velocity of the object. Objects with larger surface areas and higher velocities experience greater air resistance.
Comparing the Coin and the Paper:
- The coin is denser and has a smaller surface area compared to the piece of paper.
- The piece of paper is less dense and has a larger surface area compared to the coin.
Effect of Air Resistance:
- The coin, being denser and having a smaller surface area, experiences less air resistance.
- The piece of paper, being less dense and having a larger surface area, experiences more air resistance.
In a Vacuum:
- A vacuum is a space devoid of air or any other matter.
- In a vacuum, there is no air resistance acting on objects.
- Therefore, both the coin and the piece of paper would fall without any hindrance from air resistance.
Outcome in a Vacuum:
- In the absence of air resistance, both the coin and the piece of paper would fall at the same rate.
- This is due to the principle of gravitational acceleration, which states that all objects, regardless of their mass, fall towards the ground at the same rate in the absence of air resistance.
- Therefore, in a vacuum, both the coin and the piece of paper would touch the ground at the same time.
Conclusion:
In a vacuum, where there is no air resistance, both the coin and the piece of paper would touch the ground together. Therefore, option 'B' - "In vacuum both will touch the ground together" is the correct answer.
