Two different plays .. what is called??

[Tweet]

Alright boys I saw these two plays this weekend I did not have to call them my partners did but I was never sure about the ruling and the rules are so confusing.

Anyways..

1st Situation:
Runners on 1st and 2nd, Batter hits grounder that touches R1 before it passes a fielder. Now it's obvious that R1 is out and that BR gets 1st. My question is, does R2 get 3rd? Because the rule says he does if he is forced to advance, which he was when the ball was hit, but the force was removed when it touched R1 so which timing do we go by???

2nd situation:
Once again runners on 1st and 2nd, ball is hit towards Shortstop. R2 interferes with the fielder making the catch. Now R2 is out. Is either of R1 or BR out and if BR is out, does R1 have to go back to first base.

Thanks gentlemen
