Homework Help: Physics: Manitude of Surface Charge on Dielectric

Posted by Phil-- HELP NEEDED ASAP on Friday, May 10, 2013 at 2:38pm.

An empty capacitor has a capacitance of 1.86 μF and is connected to a 12-V battery. A dielectric material (κ = 4.5) is inserted between the plates of this capacitor. What is the magnitude of the surface charge on the dielectric that is adjacent to either plate of the capacitor? (Hint: The surface charge is equal to the difference in charge on the plates with and without the dielectric.)
