Karma Ibarra · Answer 1

When a charged amber rod is brought near the tiny bits of paper. The bits of paper are neutral. There is an electrostatic force of attraction between the amber rod and tiny bits of paper.

The charged amber rod attracts or repel the bits of paper depending on the charge of amber rod. The electrostatic force is much stronger than the gravitational force.

Therefore, a charged amber rod can lift tiny bits of paper despite being under the gravitational force of the entire mass of the earth.
