The figure shows the variation of potential energy of a particle as a function pf x, the x-coordination 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 `25J`, then it can found in the region
A
`(a)-10ltxlt-5` and `6ltxlt15`
B
`(b)-10ltxlt0` and `6 ltxlt10`
C
`(c)-5ltxlt6`
D
`(d)-10ltxlt10`
Text Solution
Verified by Experts
The correct Answer is:
A
`U=E-K=25-K` Since, `Kge0` `:. U le 25J`
