The figure shows the variation of potential energy of a particle as a funcation of x, the x-coordinate of the region. It has been assumed that potential energy depends only on `x`. For all other values `x, U` is zero. i.e. for` x lt - 10` and `x gt 15, U = 0`. If total mechanical energy of the particle is `-40J`, then it can be found in region.
A
`xlt10` and `xgt15`
B
`-10ltxlt5` and `6ltxlt15`
C
`10ltxlt15`
D
It is not possible
Text Solution
Verified by Experts
The correct Answer is:
D
