select the correct answer\nlucas rubs a plastic ruler on his sweater. he waves the ruler above a pile of shredded paper and notices that the pieces of paper get attracted to the ruler. which attractive force is responsible for this?\na. tension force\nb. normal force\nc. magnetic force\nd. electric force

Answer

Brief Explanations:

Rubbing a plastic ruler on a sweater generates static electricity (electric charge). A charged object attracts neutral objects like shredded paper via electric force. Tension (A) and normal (B) forces are contact forces, not applicable here. Magnetic force (C) requires magnetic materials, which plastic and paper are not.

Answer:

D. electric force
