Question

1. rub a balloon on the sweater and stick it to the sweater. observe what happens to the charges found on the sweater and balloon as you rub them together. fill in the chart below with your observations.

describe the charges on the sweater:
(+ or -) \ttype here

Explanation:

When a balloon is rubbed on a sweater, electrons transfer from the sweater to the balloon. The sweater loses electrons, so it becomes positively charged (+) because protons (positive charge) now outnumber electrons (negative charge) in the sweater's atoms.

Answer:

+ (The sweater becomes positively charged as it loses electrons to the balloon during rubbing.)
