iPad 3:45 PM e edugen wileyplus. com ysics, Practice Gradebook ORION Assignment ssignment UNTER VERSION BACK NEXT CES Chapter 19, Problem 46 Go The same voltage is applied between the plates of two different capacitors. When used with capacitor A, this v causes the capacitor to store 23 uc of charge and 3.3 x 10 5 J of energy. When used with capacitor B, which has a 39 capacitance of 5.0 F, this voltage causes the capacitor to store a charge that has a magnitude of QB. Determine qe.

Q = CV
W = (0.5)CV^2
First capacitor
Q = CV
23x10^-6 = CV
C = (23x10^-6)/V
W = (0.5)CV^2
(3.3x10^-5) = (0.5)(23x10^-6/V)(V^2)
(3.3x10^-5) = (11.5x10^-6)V
V = (3.3x10^-5) / (11.5x10^-6) = 2.8695 volts
Cap B
Q = CV
Q = 5.0x10^-6 x 2.8695 = 14.3475 uC
qB = 14.3475 uC
