Questions based on circular motion

An air puck of mass 0.034 kg is tied to a string and allowed to revolve in a circle of radius 1.2 m on a frictionless horizontal surface. The other end of the string passes through a hole in the center of the surface, and a mass of 1.7 kg is tied to it, as shown in the figure. The suspended mass remains in equilibrium while the puck revolves on the surface.
The acceleration of gravity is 9.81 m/s2 .

a) What is the magnitude of the force that maintains circular motion acting on the puck?

b) What is the linear speed of the puck?

According to the information provided we have one string that connects two objects. On one of the ends is a puck that is revolving on a horizontal, frictionless surface and on the other we have an object that is suspended freely.

The force with which the object that is suspended pulls...
