the answer i keep getting is wrong ... help?
Two parallel plates of area 110 cm2 are given charges of equal magnitudes 9.6 × 10-7 C but opposite signs. The electric field within the dielectric material filling the space between the plates is 4.2 × 106 V/m.
(a) Calculate the dielectric constant of the material.
(b) Determine the magnitude of the charge induced on each dielectric surface.
k=q/(E*A*epsilon_0)
q'=q(1-(1/k))
k=q/(E*A*epsilon_0)
=9.6E-7/(4.2E6*110E-4*8.85E-12)
=2.3
q'=q(1-(1/k))
=9.6E-7(1-(1/2.3))
=5.4E-7
