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.

Options

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.

Explanation

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))`
