Answer:
D. Newton's first law
Explanation:
Newton's first law of inertia says that an object will remain how it is, unless affected by an outside force. In this case, the plates want to remain stationary(not moving). Therefore, if you pull the table cloth fast enough, the force of friction produced will be small enough so that the Inertia of the plates will overcome the force of friction.
Pressure is the force acting per unit area and increases with increase in the weight of a body.
<h3>What is pressure?</h3>
Pressure is defined as the force acting per unit area of a body.
Pressure depends upon the amount of force on an object and the size of the area the force pushes or pulls on.
The greater the amount of weight pressing on an object, the greater the amount of pressure.
Of the following objects air, ice, plastic, and gold, gold is the most dense.
A dense object will produce more pressure than one that is not dense since it exerts a greater force per unit area.
Solids exert pressure because gravity is pulling downward on the object.
It is not true that the human body has more pressure sensors in the legs than in the fingertips as pressure sensors are more in fingertips.
Therefore, pressure is the force acting per unit area and increases with increase in the weight of a body.

Answer:
Minimum speed will be equal to 2.213 m/sec
Explanation:
We have given radius of the r = 2 m
Coefficient of friction
At minimum speed frictional force will be equal to centripetal force
So
So the minimum speed will be equal to 2.213 m/sec
