Assertion: A solid sphere and a hollow sphere are rolling on ground with same total kinetic energies. if translational kinetic energy of solid sphere is K, then translational kinetic energy of follow sphere should be greater than K.
Reason: In case of hollow sphere rotational kinetic energy is less than its translational kinetic energy.

A

If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

B

If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

C

If assertion is true, but the reaction is false.

D

If assertion is false but the reason is true.

Text Solution

Verified by Experts

Solid sphere, `(K_(R))/(K_(T))=(2)/(5)`
`thereforeK_(R)=(2)/(7)K_("total")` and `K_(T)=(5)/(7)K_("Total")`
Hollow sphere, `(K_(R))/(K_(T))=(2)/(3)`
`thereforeK_(R)=(2)/(5)K_("total")` and `K_(T)=(3)/(5)K_("total")`
