Answer #1

Yes, a charged body (positive or negative) attract a non charged objects.

This thing can be explained by the phenomenon of Electromagnetic induction. When a charged body is brought close enough to a non charged body its excess electron/ proton can cause changes in the electronics distribution pattern (uncharged body) and causes to develop opposite polarity (positive/ negative) and hence generate electrostatic attractive force and hence causes attraction.

Example of this is when a charged comb is brought near uncharged paper pieces it attract them and stick to it. This will happen even if it is uncharged metal pieces.

Electric charge polarization is the ultimate reason. Another example is attraction between charged sphere and a dielectric sphere.

    1 a) We charge a metal sphere with a positive charge. Now we move an neutral metal sphere, which is well insulated from ground, so that it is close to, but not touching the charged sphere. Draw a charge diagram that shows the charge distributions on both spheres. b) We again charge a metal sphere with a positive charge. Now we ground a second sphere and, keeping it grounded, we move it close to, but not touching, the charged sphere....

    You’d like to know the sign (positive or negative) of your piece of charged tape. How might you determine the sign of charge on your tape? Keep in mind that neutral uncharged matter is attracted to both positive and negative charge. How do you think one would make two OPPOSITELY charged pieces of tape? Describe a process that would allow you to make two pieces of oppositely charged tapes and how you know that they would be oppositely charged.
