Why can't coulomb's law be applied to charged object that are very close to each other?

Actually Coulombs law is applicable only for point charges but not for bodies.
But while calculating the electrostatic force between two spherical charged bodies they supposed as point masses(objects) but the distance seperation should be more greater than their radii. Otherwise the charge on one body can influence charge on another body.

What is a charging a neutral object by bringing it close to a charged object?
induction
What attract when a charged object is brought close to an uncharged object use?
If positively charged body is brought near then opposite charges i.e. negative charges are induced and hence attraction occurs
What can happen when an charged object can be brought near an uncharged object?
A neutrally charged object can still be affected by a charged object. If a neutrally charged object is being approached by a negatively charged objects, the electrons within the neutrally charged object will migrate to the other side (as the two negative charges repel), leaving the side closes to the negative object positive. Protons do not move. From there, the protons are attracted to the electrons, therefore moving the 'uncharged' object.
What effect does a negative object have on a neutral object?
If the event horizon (space, in this case) of one of the items is breeched by the other and touch, the neutral object becomes negatively charged. If they never touch, they both remain in their present condition. The neutral object's condition will never affect the charge of the negatively charged object, whether they touch or do not touch. The negatively charged item's condition will never change, regardless of physical touch between the two items. ***************Contributed by Czar Acumen*******************
What object in space exerts force on another object that is close to it?
Every single object in space exerts a force on every single other object. They don't even have to be close.

Can you still be charged any fees after you close a credit card account?
You can be charged any fees that were applicable to the account when it was still open. Yes, fees and interests will still be applied as long as there is an account balance.
What causes a pithball to move in an experiment involving a pithball electroscope?
electrons jump onto or off the neutral ball when a charged object comes close to it
Does a negative charge repel a uncharged object?
-- They can if the gravitational force of attraction is greater than the electrostatic force of repulsion between them. -- They also can if they're connected by a rubber band that has been stretched. -- But if the only force between them is the electrostatic force due to their charges, then they must always repel, because their charges have the same sign.
When a negatively charged object approaches a neutral object what sort of charge is induced on the neutral object?
None. That said, most neutral objects we meet in everyday life are composed of positively and negatively charged objects which simply cancel out to give an overall neutral object. This is important because they can create Van der Waal forces, since the positive is a bit stronger than the negative in some areas very close to the object, and vice versa.
Is close the door a direct object?
No, "close the door" is a verb phrase, with "close" as the main verb and "the door" as the object of the verb. In this case, "the door" is the direct object of the verb.
What is the definition of applied?
Put close to or in contact with.
