Question

A student attaches a rope to the handle of a chest loaded with few books , books while the other end of the rope is tied to a scale. The student pulls the scale with just enough force to set the chest in motion and records the force applied on the spring scale. The student repeats the experiment with more books in the chest and records the data in a table.

Answer 1

Answer:

B. As the mass of the chest increases, more force is required to pull it.

Explanation:

Option B is the correct that can be concluded from the data.

From the data, we can see that the mass of the chest is on the increase; it increases from 50, 75, 100, 150 and to 175. Also, in the force column, we can see an increment in the force also; from 0.25, 0.50, 1.15, 1.50 and to 1.70. So, from this data, we discover that as the mass increases, the force needed to pull it increases also.  

Moreover, this is true even logically. If you want to pull an object with a heavy, more force will be required to pull it. Therefore, Option B is the correct answer.
