Same object movement in 2 player game

Options
I have general question here for multiplayer game implementation.
I want to move ball on screen for 2d game and for 2 players only.

How to accommodate movement of ball in two devices?

I have gone through tutorial available on website but each device create new instance of game object which contain PhotonView.
But for my case I want interaction in same object for both devices. I don't know how to create this type environment and don't want any jerk in movement.

Thanks for your support and I am happy with environment that Photon provide.
