When does attraction of repulsion occur when unlike material brought nearer to each other?

attraction and repulsion depends on the charges of the materials you are using if two objects have the same charge then repulsion is going to occur but if two objects have opposite charge attraction will occur. the charge of the material is depended in how many protons (+) and electrons (-) and object has for example if your robe a plastic stick on the fur the fur would be positive and the plastic stick will be negative.

When a comb rubbed with dry hair why attracts small bits of paper?
when we rub the plastic scale against the hair it loses the electrons and whenever an object loses electrons it becomes positively charged .When this positively charged plastic scale brought nearer to paper pieces induces charge on it and electrons revolving in discrete orbits are attracted and nucleus is pushed back so that repulsion do not take place.

What kind of charge the electroscope can detect?
The sphere of an electroscope is always neutral at first. Let's say a negative ebonite rod is brought close but not touching the sphere. (The entire electroscope is neutral). The electrons in the electroscope will want to repell the electrons in the rod so the electrons in the electroscope move down into the 2 leaves and then repell because there is a high concentration of negatives. When the ebonite rod is removed, the leaves go back to their straight position. The electroscope is always neutral but only a charge distibution occured. The number of protons and electrons remain the same. However if a charged rod touches the sphere then the electroscope will be charged because it a conductor and the charge from the rod transfers to the electroscope because the rod's caharges want to attarct to the electroscope's opposite charges. This is called charging by contact.
What will happen if a positively charge rod is brought near a metal washer?
Since a metal washer is neutral, the positive rod will make all the negatively charged electrons bunch up towards the front of the washer and nearer to the rod whereas the protons in the washer would repel from the rod and move to the back of the washer.

Does the gravitational attraction between earth and an asteroid decrease as the asteroid approaches earth?
The gravitational force (or attraction) between any two objects increases as the distance between them decreases. Thus, as an asteroid approaches Earth, the Earth's gravitational pull will increase as it gets nearer.
