Charge density would be more where the curvature is more. So pointed surface would have max charge density. Hence there is a chance of electrical discharge at the sharp points. This is known as Corona Discharge or Action of Points

What is the charge density for a conductor?
The charge density inside a conductor is always zero
Can iron absorb EMF?
No, as a conductor an EMF would be distributed through-out the metal body.
How does one charge a conductor negatively if you have only a positively charged rod?
1ST. ground the conductor 2nd. move the positive rod CLOSE but NOT TOCUH the conductor u r trying to charge. 3. REMOVE the grouding wire on the conductor
What is the electric field on the surface of the conductor?
The field is zero inside only if any charge is evenly distributed on the surface. That's a mathematical theorem, sorry I don't have the proof handy. But when you measure the electric field inside a charged sphere, the charge you use might be large enough to redistribute the surface charge. In this case the electric field will not be zero. Only if you measure at the centre.
Why is difficult to change a metallic conductor which is held with hands?
It is difficult to charge a metallic conductor that is held with hands because the charge generated will be grounded through our bodies.
Why only one end of metal rod cannot be charged?
Metal is a good conductor. Any charge will quickly be distributed over the entire metal piece.
What is the charge density for a conductor?
The charge density inside a conductor is always zero
The ability of a conductor to take on a charge is called its?
The ability of a conductor to take on charge is called its conductance.
Which metal serves the best conductor of electric charge?
the metal that serves as the best conductor of electric charge is the METAL
When an electric charge moves through a conductor there is an electric in the conductor?
current
Where does the excess charge on a copper rod flow to if you don't use an insulator?
If you connect the rod with a conductor, part of the charge will flow to the conductor.
What is the property of a conductor that opposes the flow of charge passing through it is called?
property of a conductor that opposes the flow of charge passing through it
What charge does an object have when proton and electrons are evenly distributed?
the object will have neutral charge
Why is it difficult to charge a metallic conductor which is held with the hands why is it easy charged a non conductor although it is held by the hands?

Can iron absorb EMF?
No, as a conductor an EMF would be distributed through-out the metal body.
If a conductor is placed in a uniform electric field does the conductor gain any charge?
The conductor will not gain any charge that is not placed on it by you. However, the electric field will displace the free charges already within the conductor (by its nature) such that there will be a non-uniform surface charge density. Remember: a conductor must have zero electric field inside it, so the charges rearrange to cancel the external E-field. Again, this only repositions the existing charge, but it does not add or remove any charge.
