    The object which is positively charged will always transfer the electrons to the negatively charged objects. An example in the CGP book is between a positively charged Actene rod and a negatively charged cloth, whereby electrons are transferred from the Actene rod to the cloth.

    There is no definite way to know it just depends on the objects you are rubbing. For us, all we need to know is the polythene and acetate rod
