WHICH OF THESE 4 MATERIALS,WHEN RUBBED AGAINST EACH OF THE OTHER THREE,WILL BECOME POSITIVELY CHARGED EACH TIME? A)PERSPEX B)POLYESTER B)POLYSTYRENE C)PLASTIC WRAP
Perspex is the correct answer
As perspex lies above all the other three options in the triboelectric chart, so, it loses
electrons when rubbed with any of the three materials thus acquires positive charge each time.
