Select odd man out(incorrect) from the following expressions for kinet

1.	Select odd man out(incorrect) from the following expressions for kinetic energy in pure rolling.
Answer» In pure ROLLING K.E. `=(K.E.)_("TRANS")+(K.E.)_("Rot")` In pure rolling K.E. `=1/2 mv_(CM)^(2)+1/2I_(CM)omega^(2)` In pure rolling `K.E. =1/2mv^(2)` In pure rolling kinetic energy with reference to centre of mass is K.E. `=1/2mv_(CM)^(2)(1+K^(2)//R^(2))` SOLUTION :It is an incorrect expression. It is not for pure rolling.
