Question

A chapati maker is a machine which converts balls of dough into chapattis. What effect of force comes into play in this process ?
A. Compressive Force
B. Expansive Force
C. Electric Force
D. Magnetic Force

Answer 1

Hint: The given question is related to the application of a machine that converts balls of dough into chapattis. The machine is known as a chapati maker. The machine employs the force to a constructive use and makes the balls of dough into chapatis without much effort or force being applied.

Complete answer:
In the given question, we have to discuss the application of a machine known as chapati maker and what effect of the force applied comes into play in the process of making the round chapatis from the balls of dough. There are various effects of force which can be seen in our day to day life.

To find the effect of force that comes into play in the given situation, we have to first understand clearly what the force does. The force applied by the machine or chapati maker converts the balls of dough into flat round chapatis. So, the ball of the dough is expanded as the force is applied on it to get into a flat round shape of a chapati.Hence, the effect of force that comes into play in this process is Expansion force.

Hence, the correct answer is option B.

Note: Force is a simple push or pull. It is the interaction with an object that can make an object change its velocity or to accelerate. A force acting on an object can change its shape, size or velocity. In the case given to us in the question, the force changes the shape of the dough ball and thus the expansive force effect comes into play in the process.
