1.	Equal torques are applied on acylinder and a sphere. Both have same mass and radius rotates about its axis and sphere rotates about one of its diameter. Which will rotates acquire greater speed and why?
Answer» SOLUTION :`TAU=I , alpha, alpha=(tau)/(I)` `alpha` in cylinder, `alpha_(C)=(tau)/(I_(C))` `alpha` in sphere, `alpha_(s)=(tau)/(I_(S))` `(alpha_(C))/(alpha_(S))=(I_(S))/(I_(C))=((2)/(5)MR^(2))/(MR^(2))=(2)/(3)`
