Passage -II 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 zro, i.e. for x lt -10 and x gt15,U=0. If total mechanical energy of the particle is 25J, then it can be found in region
