The electric flux density of a surface with permittivity of 2 is given by 12 units. What the flux density of the surface in air?

A)

0

B)

1/6

C)

6

D)

24

Correct Answer : Option (C) : 6

Explanation : The relation between electric field and permittivity is given by Dt1/Dt2 = ε1/ε2. Put Dt1 = 12, ε1 = 2 and ε2 =1, we get Dt2 = 12 x 1/ 2 = 6 units.
