In the figure shown A, B and C are three points on the circumference of a disc. Let `v_(A),v_(B)` and `v_(c)` are speeds of these three points then
`v_(c)gtv_(B)gtv_(A)`
Reason: In case of rotaional plus translational motion of a rigid body, net speed of any point (other than centre of mass) is greater than, less than or equal to the speed of centre of mass.

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.

Verified by Experts

At `C` two terms `v` and `Romega `are `0^(@)` at `A` they are at `180^(@)` and a B they are at `90^(@)`
`thereforev_(C)=v+Romega`
`v_(A)=v-Romega`
and `v_(B)=sqrt(v^(2)+(Romega)^(2))`
