A rocket is moving in a gravity free space with a constant acceleration of `2 ms^(-2)` along +x direction (see figure). The length of a chamber inside the rocket is 4 m. A ball is thrown from the left end of the chamber in +x direction with a speed of `0.3 ms^(-1)` from its right end relative to the rocket. The time in seconds when the two balls hit each other is

A rocket is moving in a gravity free space with a constant acceleration of 2 m//s^(2) along + x direction (see figure). The length of a chamber inside the rocket is 4 m . A ball is thrown from the left end of the chamber in + x direction with a speed of 0.3 m//s relative to the rocket . At the same time , another ball is thrown in + x direction with a speed of 0.2 m//s drom its right end relative to the rocket . The time in seconds when the two balls hit each other is
