MCQ
Two trains $A$ and $B$ are running in the same direction on parallel rails such that $A$ is faster than $B$ . Packets of equal weight are transferred between them. What will happen due to this
  • A
    $A$ will be accelerated but $B$ will be retarded
  • ✓
    $B$ will be accelerated but $A$ will be retarded
  • C
    there will be no change in $A$ but $B$ will be accelerated
  • D
    there will be no change in $B$ , but $A$ will be accelerated
✓

Answer

Correct option: B.
$B$ will be accelerated but $A$ will be retarded
b
Packet from $A$ falls with greater momentum on $B$ . Therefore, $B$ is slightly accelerated
