Why does a charged particle attract light,neutral particles?

Two identical spherical conductors $B$ and $C$ have equal radii and carry equal charges. They repel each other with a force $F$ when placed at a certain distance apart. $A$ third identical spherical conductor $A$,which is uncharged,is brought in contact with $B$ and then removed. It is then brought in contact with $C$ and removed. What is the new force of repulsion between $B$ and $C$?

There are two metallic spheres of same radii but one is solid and the other is hollow, then

Fill in the blanks:
$(i)$ $A$ static charge produces a ...... field around it. (Electric,Magnetic)
$(ii)$ $A$ moving charge produces a ...... field around it.

The electric charge on an $\alpha$-particle is ....... .
