If you were given a positively-charged rod to charge an object by induction what charge will the object get?
When an object is rubbed with a charged rod, the object shares the charge so that both have a charge of the same sign. In contrast, charging by induction gives an object the charge opposite that of the charged rod. so your object would be negatively charged.
Is plastic ruler gets attracted towards pieces of paper when rubbed with oily hair?
when rubbed with hair, ruler acquires some charge due to static electricity...becomes charged body and attracts tiny pieces of paper towards it.
How to charge an object by friction?
An object can be charged by friction when rubbed against another surface such asa) polythene rod rubbed against a woollen cloth.This occurred because the woollen cloth lost some of it negative charges when it was rubbed, the negative charges was then transferred to the polythene rod. Now the polythene rod has been charge by friction.For proof... after it has been charged,place the polythene rod next to some *very small bits of paper and see what happens.
Can a negative charged object attract other negative charged objects?
objects can be negatively charged when it is rubbed with another object; a woolen cloth for example. this is because the electrons from the woolen cloth will be transferred to the object which is being rubbed! only electrons can be transferred to the object and make the object becomes negatively charged.
Why does a charged glass rod attract charged plastic straw?
it is becuase when a glas rod charged by rubbing a cloth it aquires positive charge and when a plastic straw is charged by rubbing a cloth it aquires negative charge. Therefore a charged glass rod attracts a charged plastic rod.

What type of charge does plastic collect when rubbed?
positive

What happens to the atoms in an object to generate a charge imbalance when it is rubbed with a duster?
I think you mean 'static electricity', it happens when the two objects exchange electrons, so the object will be charged either positively or negatively.
Why does a charged glass rod attract charged plastic straw?
it is becuase when a glas rod charged by rubbing a cloth it aquires positive charge and when a plastic straw is charged by rubbing a cloth it aquires negative charge. Therefore a charged glass rod attracts a charged plastic rod.
How does an object get a positive or a negative charge?
An object gives up one or more protons to get a positively charged objects and absorbs one or more electrons to get a negatively charged objects. This happens when two objects are rubbed together (ex. when you rub your feet on the carpet to give some one a shock;rubbing balloon on one's hair)
What charge do you get if glass is rubbed with silk?
the silk will rub of the electrons on the silk, leaving the glass positively charged
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.
In a neutral object has been charged by friction to a charge of one pC what has happened to it electrically?
Approx. 6.24 x 106 electrons have rubbed either onto it or off of it during the friction, leaving the net charge on it unbalanced by 10-12 coulomb.
What charge does a acetate rod acquire when rubbed with a duster?
The acetate rod loses electrons and becomes positively charged.
