Partition Problem with Data Types and File Group

 Q1) I have created Partition function on DateTime data type on A column, which belongs to 50 tables only, 10 tables have to DateTime but its B Column. So Can I Create the Partition on B Column for those 10 Tables?

Q2) Can I use DateTime Data type as Partition data type and add the Date column as Partitioning Key Column?

Q3) Is if possible to have single filegroup belongs to multiple Partition Function?( Performance Side)
