Question

A charged conductor produces an electric field. of intensity 103 V/m just outside its surface in vacuum. Then, it produces the electric field of intensity E just outside its surface, when it is placed in a medium of dielectric constant 4. The value of E will be (A) 400 V/m (B) 450 V/m (C) 250 V/m (D) 150 V/m

Given, electric field produced by charged conductor in vacuum,

E_{0} = 1 0^{3} V / m

Electric field produced by charged conductor; when it is placed in medium of
dielectrics

(K = 4) is E = \frac{E _{0}}{K} = \frac{1 0 ^{3}}{4} = 250 V / m

Q. A charged conductor produces an electric field. of intensity $1 0^{3} V / m$ just outside its surface in vacuum. Then, it produces the electric field of intensity $E$ just outside its surface, when it is placed in a medium of dielectric constant $4$ . The value of $E$ will be

$400 V / m$

$450 V / m$

$250 V / m$

$150 V / m$
