Tow particles `X` and `Y`, of equal mass and with unequal positive charges , are free to move and are initially far away from each other . With `Y` at rest , `X` begins to move towards it with initial v elocity `U`. After a long time , finally .

A

`X` will stop , `Y` will move with velocity `u`.

B

`X` and `Y` will both move with velocityies ` u//2` each .

C

`X` will stop , `Y` willl move with velocity ` lt u`.

D

both will move with velocityes ` ltu//2.s

Text Solution

Verified by Experts

The correct Answer is:
A
Since `X` is experiencing force opposite to is is velocity so it will finally stip and from the conservation of linear momentum `Y` will move with velocity `u`.
