Question

question 14 of 15
how does rubbing one object on another create static electricity?
a. rubbing removes all electrons from one object.
b. the rubbing moves electrons to the object that holds them more tightly.
c. rubbing causes charging by induction to occur.
d. the friction from rubbing creates electrons as a by - product of the heat.

Explanation:

When two objects are rubbed together, electrons can be transferred. The object with a greater attraction for electrons (higher electron - affinity) will gain electrons. Option A is incorrect as it's impossible to remove all electrons. Charging by induction (Option C) is a different process where a charged object induces a charge in another without direct contact. Electrons are not created by friction (Option D); they are just transferred.

Answer:

B. The rubbing moves electrons to the object that holds them more tightly.
