Group the following examples as a pull or a push or both.
(i) opening a drawer
(ii) opening or shutting a door
(iii) hitting a ball

(A) Pull - (i)
Pull and Push - (ii)
Push - (iii)
(A) Pull - (ii)
Pull and Push - None
Push - (i and iii)
(C) All are examples of pushing
(D) All are examples of pulling

Hint: We will first understand what a pull or a push force is and then try to give the answer to our above problem. In general terms, a push force is described as a force which when applied on a body generates a sense of push on the body. And, a pull force is described as a force which moves the body by applying a force by pulling it. Using this analogy, we shall proceed ahead.

Complete answer:
We will check for each option in the problem and decide which of them is acting as a pull force and a push force.
In our first case, we have to describe the force while opening a drawer. Now, when we open a drawer, we pull the knob of the drawer and open it up. Thus, it is a pull force only not a push force.
Now, in the second case, we have to open or shut the door. While opening a door, we pull the door towards us and apply a pull force on the door. But, while shutting the door we apply a push to the door. Thus, in this case we saw the use of both a push force and a pull force.
And now coming to our last case, hitting a ball. When we hit a ball with a bat or give it a kick, we are actually pushing the ball away from us by applying great force on it. Hence, hitting a ball falls under the push force.
Thus, our final answer should be:
Pull - (i)
Pull and Push - (ii)
Push - (iii)

So, the correct answer is “Option A”.

Note: A simple way to analyze a push or a pull force is that, while pulling an object the direction of force (observed) is away from the object and towards us. And, while pushing an object the direction of force (observed) is towards the object and away from us.
