A 100 kg object and a 10 kg object are dropped simultaneously in a vacuum. Which of the following statements is true?



Both objects will accelerate at 9.8 m/s2


The 100 kg object will accelerate faster than the 10 kg object.


The 10 kg object will accelerate faster than the 100 kg object.


Air resistance will slow the fall of the 100 kg object more than the 10 kg object.

Sagot :

In a vacuum, all objects fall at the same rate. Meaning that the 100 kg ball will fall at the same speed as the 10 kg ball. Assuming that both objects share the same starting acceleration, they will keep that acceleration until the fall is stopped.
In other words, your answer is the first one, Both objects will accelerate at 9.8 m/s

Answer:

Both objects will accelerate at 9.8 m/s².

Explanation:

According to given condition, a 100 kg object and a 10 kg object are dropped simultaneously in a vacuum. If there is no air resistance, when two objects of same or different masses will reach the ground at same time. The rate of descent does not depend on the amount of matter contained inside the object.

In the vacuum, no air resistance is present. Both of the objects will accelerate at 9.8 m/s² i.e. under the action of gravity.

So, the correct option is (a). Hence, this is the required solution.
