Opening the door of a refrigerator, playing tug of war, and taking out water from a well using a rope attached to a bucket all involve the application of mechanical force. However, hitting a cricket ball with a bat to make runs is different from the others in terms of the type of mechanical force involved.
Type of Mechanical Force:
1. Opening the door of a refrigerator: This action involves exerting a pulling force on the handle or knob of the refrigerator door. The force applied is in the direction opposite to the closed position of the door, and it overcomes the resistance provided by the door latch or seal.
2. Playing tug of war: In this activity, two teams pull on opposite ends of a rope, trying to overpower each other. The force applied is in the opposite directions, and the team that exerts a greater force in their direction wins. This force is known as tension force.
3. Taking out water from a well using a rope attached to a bucket: This action involves applying a pulling force on the rope to lift the bucket filled with water from the well. The force applied is in the upward direction, opposing the force of gravity acting on the bucket.
4. Hitting the cricket ball with a bat to make runs: This action involves striking the cricket ball with a bat to propel it in a desired direction. The force applied in this case is an impact force, which is the result of the collision between the bat and the ball.
Explanation:
The odd one out is option 'C' - hitting the cricket ball with a bat to make runs because it involves an impact force, whereas the other actions involve pulling or lifting forces. In the case of hitting a cricket ball, the force is not applied continuously over a period of time. Instead, it is a sudden force applied at the moment of impact between the bat and the ball. This force causes the ball to change its direction and gain momentum.
While opening the door of a refrigerator, playing tug of war, and taking out water from a well using a rope attached to a bucket, the force is applied continuously and in a specific direction to achieve the desired outcome. These actions require sustained force to overcome resistance or gravity.

Hitting the cricket ball with a bat to make a run shows pushing action while rest three show pulling action.
