an object m is tied to one end of a string, moves in a circle with a constant speed v on a horizontal frictionless table. the second end of the string is connected to a big mass m and goes through a small hole in the table. what is the value of m if it stays in equilibrium?

Respuesta :

The value of M that goes through a small hole in the table if it stays in equilibrium is mv²/ rg.

The force acting on object m is the centripetal force.

Fc = m v² / r

Mass = m

Velocity = v

Radius = r

The force acting on object M is the gravitational force,

Fg = M g

g = Acceleration due to gravity

Since the system is at equilibrium,

Fc - Fg = 0

m v² / r = M g

M = m v² / r g

Therefore, the value of M, if it stays in equilibrium, is mv² / rg.

Equilibrium, in physics, is the condition of a machine when neither its state of motion nor its inner electricity nation tends to alternate with time. The balance of physics is the nation of the device whilst neither the kinetic state nor the inner strength nation of the system modifications through the years. An easy machine is in equilibrium when it receives neither linear nor angular acceleration.

A device is stated to be in equilibrium if it does not tend to go through any further change of its own. Any similar change should be produced by means of an outside approach (e.g. pressure). A body is stated to be in translational equilibrium if the sum of all the forces performing at the body is 0. Equilibrium is the country in which market supply and calls for stability each different, and as a result, costs become stable.
