Answer 1

I think it's C.

Step-by-step explanation:

I'm not a smarty-pants lol but I hope I can help :)

Answer 2

The method of charging John used is that John charges the rod through friction, then charges the electroscope through induction. Friction occurs because of the interaction between two substances that are rubbed together producing a charge whereas induction occurs is the production of electric current through various magnetic field.
