Pulling a Cloth from a Table – Rankers Physics

Definition of Force Inertia and First Law: Practice Problem & Solution

If a cloth covers a table and some dishes are kept on it, then the cloth can be pulled out without dislodging the dishes from the table by pulling the cloth suddenly. The dishes will remain on table due to
Work-energy theorem
For every action, there is an equal and opposite reaction
Inertia of motion
Inertia of rest

Solution Explained:

To solve this problem, we apply the core principles of Definition of Force Inertia and First Law. Understanding the underlying formula is key to arriving at the correct answer below:

According to Newton's First Law, when the cloth is suddenly pulled, the dishes tend to maintain their state of rest due to the inertia of rest.

1. Which one of the following statements is incorrect? (2018)
2. Assertion (A): The acceleration of a body moving down on a rough inclined plane is greater than the acceleration due to gravity. Reason (R): The body is able to slide on an inclined plane only when its acceleration is greater than acceleration due to gravity.  
3. A uniform chain of length \( L \) is placed on a rough horizontal table with some part hanging below the table. If the length of the hanging part becomes \( \frac{2L}{5} \) then the chain starts sliding on the table. The co-efficient of friction between the chain and the table is:
4. A \(3.0\text{ kg}\) mass is moving in a plane, with its x and y coordinates given by \(x = 24t^2 - 1\) and \(y = 3t^3 + 2\), where x and y are in meters and t is in second. Find the magnitude of the net force acting on this mass at \(t = 2\text{ sec}\).
5. Assertion (A): The contact force is the net force applied by the surface on the body kept on it. Reason (R): When a body is at rest on a horizontal surface then the contact force on the body by the surface must be equal to the weight of body.
