Two neutral metal spheres are separated by 0.5m when 3.0x1013 electrons are transferred from one to the other. Calculate the resultant force magnitude and whether it is attractive or repulsive.


q=Ne
F=kq1q2/r2
I think?


q=(3.0x1013)(-1.602x10-19C)
q=-4.8uC

F=(9x109)(-4.8uC)(4.8uC)/(0.5m)2
F=-0.83N [attractive]

Does this seem correct?
