Question
Exercise 24.34 70f 15 Part A onstant A parallel-plate capacitor has capacitance Co 7.50 pF when there is air between the plates. The separation between the plates is 1.00 What is the maximum magnitude of charge that can be placed on each plate if the electric field in the region between the plates is not to exceed 3.00x104 V/m? Express your answer with the appropriate units min QValue Units Submit ue Part B A dielectric with K -2.40 is inserted between the plates of the capacitor, completely filling the volume between the plates. Now what is the maximum magnitude of charge on each plate if the electric field between the plates is not to exceed 3.00x104 V/m? Express your answer with the appropriate units QValue Units Submit Request AnswerExplanation / Answer
capacitance C0 = 7.5*10^-12 F
seperation d = 1mm = 10^-3 m
charge Q = C0*V = C0*E*d
charge Q = 7.5*10^-12*3*10^4*10^-3
charge Q = 2.25*10^-10 C
==========================
part B
If dielectric is placed capacitance C = k*C0
charge Q = C*V = k*C0*E*d
charge Q = 2.4*7.5*10^-12*3*10^4*10^-3
charge Q = 5.4*10^-10 C
