A flat disk with a mass of m is tied to one end of a
string, moves in a circle with a constant speed v or
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
required value of M for it to remain in equilibrium?
a. = v²/rmg
%3D
b. = mv?/rg
С. 3
rg/mv2
d. = mv?r/g
