I need help





Sphere A is a metal sphere with a negative charge on a insulating stand. There are two Spheres named B and C exactly the same as Sphere A except not charged(neutral). If sphere B touches Sphere A then gets moved away. Then sphere B touches Sphere C. What is the charge of Sphere B and C.





I wrote Sphere B and C is neutral because charging by insulation will only reposition the electrons.

The charge on sphere B will be half the charge on sphere A. Also, C will have half A's charge.
Reply:Spher A has half from when it touched B. B and C have the other quarters each from when they shared their charge..
