D) Conservation of Charge - net charge of closed system remains constant

 

 

 

 

 

 

If 2 charges OR MORE
are brought together, their combined charge
is distributed evenly

 

 

 

 

Before contact
 
After contact


 

 

 

 

Charge evenly distributed

 


Total charge before =

total charge after

 

 

 

 

 

Ex) Metal sphere A has a charge of +12 elementary charges and identical sphere B has a charge of +16 elementary charges.

After the two spheres are brought into contact, the charge on sphere A is

a)+28 elem. charges  c)+2 elem. charges
b)-2 elem. charges  d)+14 elem. charges

d)+14 elem. charges
