55. Equal and opposite charge is given to two parallel plates. Without any space between them, the electric field is \( 3 \times 10^{5} V / m \) and with space filled with dielectric, electric field intensity is \( 1.0 \times 10^{5} V / m \). The induced charge density on the surface of the dielectric is: (a) \( 3.44 \times 10^{-6} C / m ^{2} \) (b) \( 8.8 \times 10^{-6} C / m ^{2} \) (c) \( 6.93 \times 10^{-6} C / m ^{2} \) (d) \( 1.77 \times 10^{-6} C / m ^{2} \)

Correct Answer - A
`mu = (C)/(V) = (CK)/(omega) = (3 xx 10^(8) xx 4 xx 10^(-7))/(50) = (120)/(50) = 2.4`
