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., `xlarr10` and `xgt15`, `U=0`. If the total mechanical energy of the particle is `-40J`, then it can be found in regionA. (a) `xlarr10` and `xgt15`B. (b) `-10ltxlarr5` and `6ltxlt15`C. (c) `10ltxlt15`D. (d) It is not possible |

Answer» Correct Answer - D The concept is same as above. If `E=-40J`, `K=-40-U`. It means `Ularr40` for K to be positive, but from given variations, it is clear that minimum, value of `U` is `-35J`. So this is not possible. |
