What would the charge of an atom be if it has six protons and six electrons? a. about +12 c. 6 b. about -12 d. there is no charge

If angle "a" is 25°, angle "b" is: a) equal to angle c b) less than angle c c) greater than angle c

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e
