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.

Yes. The ink sticks just as a rubbed comb attracts bits of paper.
When a glass rod is change and is placed near small bits of paper the paper bits are attracted to the rod and then replied explain?
A glass rod that is charged usually attracts the small bits of paper placed near it because it is usually electrostatically charged.
Will a comb rubbed on the hair once attract bits of paper very they come close?
yes
What is indicated when the paper bits move towards the rubbed plastic strip?
It indicates that both strips have either both positive or negative charges therefore the plastic strips repel each other.
Why do bits of paper adhere to a comb that was rubbed with a flannel cloth?
Because of a static charge caused by the rubbing.

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.
What happens when iron rod rubbed with wool cloth?
The iron rod becomes shinier and the wool cloth wears out. If you rub the same wool cloth on a hard rubber rod, the rod will become charged with static electricity and you will be able to pick up small bits of paper with it---whoopee!
Why can rubber rubbed with wool attract small bits of paper?
The reason why the pieces of paper are neutral is that they contain equal amount of positive and negative charges and so they cancel each other out. When you bring a charged plastic comb to the pieces of paper, the charge opposite to that of the plastic comb will be brought to a part of the surface of the paper where the plastic comb is. Opposite charges attract each other, and since you're holding the comb, the pieces of paper will be attracted to the comb.
How does a charged comb affect bits of paper?
The bits of paper acquire opposite charge of the comb and as unlike charge attract the bits of paper are attracted and picked up by the comb
How do you explain why a charged comb often attracts smaller bits of papers that fly away when they touch the comb?
Static electricity in the comb attracted the slightly charged paper to it, but when the paper touched the comb, their very slight charge was neutralized, which caused them to fall off.
