A smooth sphere (mass `10kg. ` negligible radius) rolls on a smooth curved surface from the point `A` with a speed of `10m//s` as shown in figure. The sphere reaches the point `D` passing through point `B`. If the ground is taken as reference . Then `[` Take `g=10m//s^(2)]`

The kinetic energy `&` the potential energy at point `B`.

A

`2500J,0J`

B

`0J,2500J`

C

`2500J,1500J`

D

`1500J,2500J`

Text Solution

Verified by Experts

The correct Answer is:
A
`ME_(B)=KE_(B)+PE_(B)=ME_(A)`
`PE_(B)=0 , KE_(B)=ME_(A)=2500J.`
