In which of the following situations will there be no torque?Chooseall that apply.
A disk of mass M and radius R has a massless string wound arounditsouter edge. One end of the string is attached to the outer edge ofthe disk. The other end of the string isattached to the ceiling. The mass is allowed to fall verticallyunder the influence of gravity as the stringunwinds like a yo-yo. The acceleration of gravity is g ..(a) Draw the free body diagram for the disk(b) Write down newtonâs law for the rectilinear motion of thecenter of mass of the disk.(c) Write down Newtonâs law for the rotation of the disk about itscenter of mass.(d) What is the relationship between the linear acceleration of thedisk and angular acceleration of thedisk.(e) Solve for the acceleration of the center of mass of thedisk.(f) What is the angular acceleration of the disk about its centerof mass ?(g) What is the tension in the string as it unwinds?
