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 - D
`V_omega = 100 V_T`
`sqrt(y/rho) = 100 sqrt(T/m)`
`y/rho = 10^4 T/m = 10^4 (T)/(rhoA)`
`T/A = (Y)/(10^4) = (10^11)/(10^4) = 10^7`
Stress `=10^7N//m^2`
