A stone with a mass of 0.70 kg is attached to one end of a string 0.80 m long. The string will break if its tension exceeds 65.0 N. The stone is whirled in a horizontal circle on a frictionless tabletop; the other end of the string remains fixed. Find the maximum speed the stone can attain without breaking the string.
Answers
Answer:
The maximum speed the stone can attain without breaking the string is 8.62 m/s .
Explanation:
Given :
Mass of stone , m = 0.7 kg .
Length of string , l = 0.8 m .
It is also given that the stone will break if its tension exceeds 65.0 N.
Now , we know tension in the rope due to rotation is equal to the centripetal acceleration .
Therefore , the maximum speed the stone can attain without breaking the string is less than or equal to 65 N .
So ,
Putting all value in above equation we get :
Therefore , maximum speed the stone can attain without breaking the string is 8.62 m/s .

You mean like a box sitting on a table.
One force is the force of gravity, pulling downward on the box.
Now, you know that the forces acting on the box must be balanced, because
if they're not, then the box would be accelerating. But it's just sitting there, so
there must be some other force, just exactly the right strength and direction to
exactly cancel the force of gravity on the box, so that the net force on it is zero.
The other force is the force of the table pushing upward on the box. It's called
the "normal force".

In everyday speech, the phrases "mass" and "weight" are frequently used interchangeably, yet they have different meanings. Weight is a measurement of how the force of gravity works upon a mass, whereas mass is a measure of the amount of matter in a material. Therefore, Weight and mass are not interchangeable terms.
What is mass ?
A body's mass is an inherent quality. Prior to the discovery of the atom and particle physics, it was widely considered to be tied to the amount of matter in a physical body.
The quantity of matter in an item is its mass. The gravitational pull exerted on a mass is known as weight. Combining the two would be confusing because workplace can affect weight.
An object's mass is a crucial indicator of how much stuff it contains. Weight is a measurement of an object's gravitational pull. It is influenced by the object's location in addition to its mass. As a result, weight is a measurement of force.
Thus, Weight and mass are not interchangeable terms.
To learn more about the mass, follow the link;

weight (N-force) = mass(kg-matter) x g
strictly in Physics, both are not interchangeable.
in normal life, weight (kg) actally means mass in Physics.
