Golf ball is hit by opponents ball and goes in hole?

Answer 1

Say player A's ball is sitting on the green, if player B's ball hit's A's ball and A goes in the hole, it must be replaced to the original position. If B's ball goes in, it is classed as holed. This scenario applies on if B hits from off the green. If he is on the green and hits A's ball he receives a two shot penalty.

Answer 2

Par four it's an eagle, par five it's an albatross.
