1 F

(b) How much charge is stored on the plates?
2 C

(c) What is the electric field between the plates?
3 N/C

(d) Find the magnitude of the charge density on each plate.
4 C/m2

(e) Without disconnecting the battery, the plates are moved fartherapart. Qualitatively, what happens to each of the previousanswers?

Explanation / Answer

area A = 0.500m2
plate separation d = 5.00mm                             =5 * 10 -3 m Voltage V = 12.00 V (a) capacitance C = A /d where = permitivity of free space =8.85 * 10 -12 C 2 / N m 2 (b). charge is stored on the plates Q = CV where V = Voltage = 12 V (c). the electric field between the plates E =V / d (d).  magnitude of the charge densityon each plate = E substitue values weget answer
