Comprehension \( \quad \) The figure shows the variation of potential energy of a particle as a function of \( x \), the \( x \)-coordinate of the region. It has been assumed that potential energy depends only on \( x \). For all other values of \( x, U \) is zero, i.e. for \( x-10 \) and \( x15 \), \( U=0 \). Based on above information answer the following questions
If total mechanical energy of the particle is \( -40 \mathrm{~J} \), then it can be found in region
(a) \( x-10 \) and \( x15 \)
(b) \( -10x-5 \) and \( 6x15 \)
(c) \( 10x15 \)
- (d) It is not possible
