A uniform circular ring rolls without slipping on a horizontal surface. At any instant, its position is as shown in the figure. Then

Options

A. section `ABC` has greater kinetic energy than section `ADC`
B. section `BC` has greater kinetic energy than section `CD`
C. section `BC` has the same kinetic energy as section `DA`
D. The section `AB, BC, CD` and `DA` have the same kinetic energy

Answer

A, B

Explanation

Since `D` is the instantaneous centre of rotation and as we go from `D` to `B` velocity increases. So upper half of the ring will have greater kinetic enegy than lower half.
