Two neutral metal spheres X n Y are placed in contact with each other on two insutating supports. A positively charged rod is brought close to X after Y is earthed with a conducting wire.

 

I would like to ask how's the distribution of charges on the spheres.

 

 

You have to go first. What do you think it will be?

Read more about induction and conduction on the net. Do it yourself!

Keep in mind that when the charge distribution is induced from the outside the charges get an additional exclamation mark.

In electrostatics, the charges will move until there is no net force acting on them.

the charge will be almost the same

ok thanks. I will figure it out by myself.
