Question

dielectric constant of helium at 0 c and one atmosphere is 1.000074 .find the dipole movement induce in each helium atom when the gas in an electric field of intensity 100 volts per meter

Answer 1

Explanation:

Solution :

Given :

Dielectric Constant ( Er )= 1.000074

Permittivity of free space( e° ) = 8.854 × 10-¹² C² / N - m²

Electric field = 100 Volt / meter

Induce dipole moment =

P. = e° ( Er - 1 ) E

= 8.854 × 10-¹² ( 1.000074 - 1 ) 100

= 8.854 × 10-¹² × 0.000074 × 100

= 8.854 × 10-¹² × 0.0074

= 0.06551 × 10-¹²

= 6.551 × 10-¹⁴ V m-² F
