Assertion : A solid sphere and a ring of same mass and radius are released simultaneously from the top of an inclined surface. The two objects roll down the plane without slipping. They reach the bottom of the incline with equal linear speeds
Reason : Decrease in potential enery for both is the same.

Options

A. If both Assertion and Reason are correct and Reason is the correct explanation of Assertion
B. If both Assertion and Reason are true but Reason is not the correct explanation of Assertion
C. If Assertion is true but Reason is fasle
D. If Assertion is false but Reason is true

Answer

D

Explanation

Total energy, `(1)/(2)mv^(2)+(1)/(2) Iomega^(2) = mgh` (for both)
`I` is different for two bodies
Hence, `v` and `omega` will be different, as `v= R omega`, but loss of potential energy is same.
