Question

rub vinyl and paper. which becomes positive and which becomes negative?

both are negative

both are positive

paper becomes negative and vinyl becomes positive

vinyl becomes negative and paper becomes positive

Explanation:

When two materials are rubbed together, electrons can be transferred. The material that gains electrons becomes negatively charged, and the one that loses electrons becomes positively charged. In the triboelectric series (a list of materials ranked according to their tendency to gain or lose electrons), vinyl has a greater tendency to gain electrons compared to paper. So when rubbed together, vinyl gains electrons (becomes negative) and paper loses electrons (becomes positive).

Answer:

vinyl becomes negative and paper becomes positive
