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
`(W_(2))/(W_(1))=((R)/(R+h))^(2)=((R)/(R+4R))^(2)=((1)/(5))^(2)=(1)/(25)`
`W_(2)=(W_(1))/(25)=(20)/(25)=0.8N`
Apparent weight is zero.`
