Please can anyone help me download a flash player to my galaxy tab 2 .10.0.
No can do. Android ended all support for Flash Player last summer (June 2012). They recommend using "Dolphin" or "Puffin" as your browser to view Flash content. Both are free in the GooglePlay store and they use server side rendering, which is important because playing Flash content with Flash Player is 'processor consumptive' and drains batteries in mobile devices. It also shortens battery life.
