A system comprises of two small spheres with the same masses `m`. initially, the spring is non deformed. the spheres set in motion in a gravity space at the velocities as shown in the diagram. The maximum elastic potential energy stored in the system isA. `(mv_(0)^(2))/(2sqrt(2))`B. `mv_(0)^(2)`C. `1/2mv_(0)^(2)`D. `2mv_(0)^(2)` |

Answer» Correct Answer - B Both the spheres will come at rest simultaneously because net momentum of system is zero. And when they comes to rest, their KE converts into elastic potential energy of spring. `U=2[1/2mv_0^2]=mv_0^2` |
