Track `OABCD` (as shown is figure) is smooth and fixed in vertical plane. What minimum speed has to be given to a particle lying at point `A`, so that it can reach point `C`?

A

`60m//s`

B

`100m//s`

C

`70m//s`

D

`80m//s`

Text Solution

Verified by Experts

The correct Answer is:
D
Apply work energy theorem between point `A` & `B` we will get
`v=sqrt(2gh)=sqrt(2xx10xx320)=80m//s`
